Sodium bicarbonate
The person that often does a steamed bread is new to sodium bicarbonate scarcely, it is the leaven dough god with necessary family implement.
Nevertheless, went up in platform of some nearsightedness frequency recently, sodium bicarbonate suddenly change one's identity was become again " the net is red " . In video, sodium bicarbonate walks out of a kitchen, dry had other line of business: Divide ferruginous, except furring, clean washing machine, connect the besmirch inside sewer, beautiful white tooth, cleared closestool... all of skill in various types of combat of it may be said is perfectness. But does sodium bicarbonate have really so magical?
Theme: Can sodium bicarbonate eliminate ferruginous, scale?
The truth
The composition of both mixes alkaline happening to react far from
Detail
Sodium bicarbonate namely bicarbonate natrium, call acerbity type sodium carbonate again, belong to acid salt, chemical type is NaHCO3, after blending in water, show alkalescent, it is a kind of crystal white solid, but normally expression is fine powder, have small salty alkalescent flavour.
Pass sodium bicarbonate to be able to use the argument that dirties except furring, make water to the net, a professional personage that does not wish to disclose a full name tells daily of science and technology the reporter, because the composition of furring is calcium of magnesium of calcium carbonate, carbonic acid, calcium sulfate, vitriolic magnesium, chloridize, magnesium chloride; And the uric dirty on closestool is a few salt kind, wait like salt of carbonate, phosphate, ammonium, these composition won't mix alkaline happening to react, only acid can get rid of they, because this saleratus cannot be used,will dirty except furring, make water.
Besides cannot dirty except furring, make water, sodium bicarbonate + white vinegar can remove ferruginous view unscientific also. Ferruginous composition is ferric oxide, alkaline reaction of ferric oxide disaccord, so sodium bicarbonate cannot divide rust. Although acetic acid is OK and slow deliquescent ferruginous, but the acetic acid density in white vinegar is only 3% , 5% , did not remove rubiginous effect basically. Use saleratus and white vinegar divide rust to scissors, can make scissors becomes blunt not only, if clean sordid, what rudimental salinity still can quicken scissors is rustily.
The accurate method that divide rust
It is OK to remove ferruginous means commonly usedly cent is physical method and chemical method two kinds. Physical method basically is the means eliminate that uses burnish ferruginous, brush with sand paper, emery wheel, steel wire for example, steel wire ball undertake burnish. Chemical method basically is to use acid and ferruginous hair to give birth to chemical reaction, achieve the goal that eliminates rust thereby. Bases is the common agent dividing rust in the life hydrochloric acid, rare vitriolic, they can react with ferric oxide. Its principle is, the agent that divide rust is permeated along the crack of rubiginous layer and foreign matter layer to steely goods surface, deliquescent to rubiginous layer and generation of foreign matter layer, flake action, make rubiginous layer, impurity and oxidation skin fall off from steely goods surface thereby. But it is certain that acid is had caustic, accordingly, when dividing rust need is worn defend take.
Theme: Can sodium bicarbonate go black head?
The truth
Can produce very big stimulation to the skin, cannot use at black head purify
Detail
Black head says blackhead again, because sebaceous glands secreted too much skin fat,be, as a result accumulation is in conduit, jam harden, blacken in the oxidation in air next those who form.
Hearsay says to need a few sodium bicarbonate powder only according to about 1 ∶ the scale dissolve of 10 at water, with make up cotton or tampon bedew apply is on nose, 10 minutes, black head is risen to came.
To this, the explanation on the net is: "Sodium bicarbonate dissolve is shown after water alkalescent. Below basic requirement, the bases grease of black head can produce saponification reaction, make glycerine and grease acerbity salt, the water-solubility of glycerine and grease acerbity salt is better, can achieve so go the effect of black head. " but report according to fruit carapace net, this saponification reaction is slower, its speed concerns with temperature of basic strength, reaction very big. If be room temperature, in sodium bicarbonate such alkalescent condition falls, calculating is not complete cannot react, wait for reaction to finish also want when day moorland is old, not be absolutely " apply ten minutes " can happen.
To this, capital medical university is accessary week of doctor of venereal division director makes the same score skin of hospital of Beijing century altar to express clearly also to the reporter: "Using sodium bicarbonate to treat black head is a rumor, it is unscientific! " sodium bicarbonate can produce very big stimulation to the skin, cannot use at black head purify. Zhou Ping tells a reporter, on medicine, sodium bicarbonate basically uses treatment acid is toxic, and it is vein inject. "It is to be in home or abroad no matter, clinical go up to do not have external use the practice of sodium bicarbonate. Clinical go up to do not have external use the practice of sodium bicarbonate..
Theme: Is sodium bicarbonate beautiful white tooth?
The truth
Can destroy a tooth inside bad situation
To dental itself generation corrodes action
Detail
Besides black head, beautiful personage of tooth Huang Ye's your daughter is pained. The net passes sodium bicarbonate to have the effect of beautiful white tooth, to this, the expert expresses, this also is unscientific.
Tooth yellow cent is inside source sex and outside source sex. Source sex tooth fizzles out outside, because have smoking,be, drink the tea, habit that drinks coffee, eat sauce for long perhaps heavy, color is deep, easy colored food, the tooth can accumulate some of pigment in this process. Source sex tooth fizzles out inside is brought about by some kind of element, happen inside dental organization.
"To inside source sex tooth is yellow, do wash tooth, gush arenaceous it is otiose. Ultrasonic washs a tooth to be not solved, sodium bicarbonate is more inextricability. Habits and customs causes source sex tooth fizzles out outside, sodium bicarbonate cannot have reaction with deposit pigment, can have attrition effect only, cannot solve the problem with yellow tooth. " Wei Hui of dentist of outpatient department of oral cavity of Er of Xiamen Siming eminent says to the reporter.
Ling of Jing of Xu of doctor of vice director of department of stomatology of the 3rd hospital says Beijing University: "Tooth of sex of the source outside be aimed at is yellow, wash tooth, polish groovily to be able to keep clear of its clean, regain dental whiteness position. If dental itself color is yellow, washing a tooth cannot be cleaned clean, can do dental beauty's white, permanent porcelain to stick a face to improve tooth yellow position. Can do dental beauty's white, permanent porcelain to stick a face to improve tooth yellow position..
Although a few research show, compare with the toothpaste photograph that does not contain bicarbonate natrium, the toothpaste that contains bicarbonate natrium has better beautiful Bai Heya effect of bacterium spot purify. But this is not meant, can brush his teeth with sodium bicarbonate directly. The expert expresses, sodium bicarbonate itself is basic material, if use sodium bicarbonate for a long time to brush one's teeth,can destroy a tooth inside bad situation, corrode action to dental itself generation.
Theme: Xiaosu after all able?
The truth
Use extensively at industry of food, medicine
Detail
Although above those saying work sodium bicarbonate is not able, but it has a lot of use really, basically be to serve as additive agent for food and antacid, be used extensively at industry of food, medicine.
The ground of the use force with the most familiar saleratus is a kitchen -- as Peng loose agent is used at bake. When it and sour reaction carbon dioxide can be released, bring about panada to expand. Can make thin pancake, cake, fast biscuit, soda biscuit and deepfry provision. Nevertheless, falling without acerbity circumstance, the pyrolysis of bicarbonate natrium can produce sodium carbonate, its alkali sex can make roast product produces ingredient of acrid, soap and present a yellow.
According to Zhejiang Xue Zhiyong of researcher of courtyard of province farming division introduces, in recent years, the feed additive that abroad already regarded cultivate as birds sodium bicarbonate (buffer) . Sodium bicarbonate regards the feed of ruminant as additive, amortize effect can have inside rumen, the acidity that can counteract ensiling feed and gastric internal cause are microbial ferment the organic acid of generation, make the environment in rumen keeps neuter, to microbial offer a good growth environment, be helpful for the assimilation of cellulose and other saccharide. The experiment makes clear, add the milk cow that feeds sodium bicarbonate, height yield a milk comes ahead of schedule, in whole secrete lacteal period maintains high yield not to decline.
The meeting when bicarbonate natrium heats releases a carbon dioxide, because this can use cut out an engine, but do not apply to the bright fire in putting out oily boiler, the gas that because its are abrupt,releases may bring about grease to splatter. When the acerbity solution that does not need in counteracting chemical lab or acerbity leak, sodium bicarbonate is OK also the use on the clique.
On medicine, bicarbonate natrium and water mix can use as antacid will treat acidity indigestion and brash; The stomach that can alleviate or reduces generation of aspirin of profess to convinced stimulates a symptom; Also can undertake ticking off add with right amount water, handle sodium bicarbonate mushy and local paint at the skin, reduce a few insects to bite and accompanied strut.
In addition, according to publishing document account, bicarbonate natrium still has weaker alexipharmic performance, it is the effective method that control fungus grows, be registered to be biology pesticide by bureau of American environmental protection, can employ is mixed at hydrotherapy pool garden pond in order to raise its total alkalinity.
