Somebody asks today small make up, the phosphoric acid of 400g they sell 2 hydrogen Potassium 3 yuan of fund only then, be a holiday? 99.9999999% be a holiday so small today make up tell to everybody tell how to drill will discern with respect to piercing eye phosphoric acid the true bogus of 2 hydrogen Potassium!
One, the pricePhosphoric acid purity of 2 hydrogen Potassium is very tall, be in basically above of 98 ％ , 99 ％ , because raw material cost is high, price of 2 hydrogen Potassium compares true phosphoric acid tall. On common market 400 grams a bag of price is in basically 14 Qian Zun are right. So, do you say 3 two your money can buy a bag of true phosphoric acid 2 hydrogen Potassium? If can, that gives small make up come to 10 bags!
True phosphoric acid 2 hydrogen Potassium, there is phosphoric acid certainly on outer packing 2 hydrogen Potassium 5 Chinese characters, and fair bid has detailed production enterprise, the site of factory, phone is mixed executive standard (executive standard is HG-2321-92) .
Read content at the same time, content marks commonly for 00-52-34, high grade phosphoric acid the 5 oxidation in 2 hydrogen Potassium 2 phosphor (P205) ≥ 51.6, oxidation Potassium (K20) 34 ％ of ≥ , if content number is medium, the first 00 mark have other number, or hind two numbers under 52, 34, small make up persuade you to change to be bought!
Mark understands this product to be comprised by nitrogen, phosphor, Potassium in the specification, still contain the microelement such as boracic, zinc, iron, conditioning agent even, grow of the high-tech noun such as factor, rare earth, it is fake more product. Phosphoric acid 2 hydrogen Potassium, phosphoric acid 2 hydrogen Potassium, it is of course besides phosphor it is potassium cough up, have anything else impossibly, also did not say to have in national level " compound model " phosphoric acid 2 hydrogen Potassium!
Pure false product
It is filling with vitriolic magnesium namely generally speaking, add hormone again
Differentiate very simple, dissolve at water, add sodium bicarbonate, having a bit bleb to arise is false phosphoric acid 2 hydrogen Potassium.
Adulterate product
quality goods phosphoric acid 2 hydrogen Potassium and vitriolic magnesium, according to 1? : ? 9 smaller perhaps proportion, mix into lump, add hormone again. To businessman of some of this kind of product even dare of brazenly do with sodium bicarbonate differentiate an experiment, even character of a person of extraordinary powers not dread your go off with detects. Alas, the businessman covers a region deep!
Differentiate:
1, still be sodium bicarbonate above all, join a few calcium nitrate after that or ammonium nitrate is calcic, white precipitation is generated is false phosphoric acid 2 hydrogen Potassium.
2, phosphoric acid aqueous solution of 2 hydrogen Potassium is transparent and colorless did not precipitate, for weak acidity, what PH test paper checks solution to be acidity is false phosphoric acid 2 hydrogen Potassium
3, 2 hydrogen Potassium adds phosphoric acid sodium bicarbonate can have bleb to appear but do not have a stink however
4, 2 hydrogen Potassium has phosphoric acid hygroscopic, if be the general meeting that pack has little salt bead, if particularly dry, it is false certainly
5, perfect crystal is abnormal, it is grain length a club completely affirmation is abnormal also
6, dissolve water. 2 hydrogen Potassium pours phosphoric acid into water, shake forcibly 34 coarse of 34 seconds Quan Rong is true, of partial dissolve is false. Want to notice nevertheless, if, you fall into water, instantly dissolve is major perhaps instantly of dissolve is a holiday! Because of mix into vitriolic magnesium, the solubility of vitriolic magnesium treats water higher namely dissolve.
7, with baked wheaten cake, what do not change is fake, changing what evaporate clean directly also is fake, in the process of the stink is fake likewise!
Good, how to differentiate phosphoric acid today 2 hydrogen Potassium tells this. Alas, buy a phosphoric acid 2 hydrogen Potassium is be nervous really, must want to use a skill in various types of combat, add piercing eye even, tired dead individual!
Small make up clew:
Crop disease is not anxious, click lower part " understanding is more " , download divine farming knowledge, pat, problem of plant diseases and insect pests is solved immediately. Quick, essence is accurate, efficient!
