How ammonium thiosulfate and ammonium sulfate mixture are extracted

Ammonium thiosulfate can be converted to ammonium sulfate: acid is added first, ammonium thiosulfate is converted to ammonium sulfite, and then hydrogen peroxide is added.

As the title suggests, it is to extract ammonium thiosulfate in the mixture of the two, if there is no way to extract it, find a way to convert ammonium thiosulfate into ammonium sulfate, please tell me the general idea, if you can give the experimental steps as soon as possible, thank you I am in a hurry, give a high score.

The ammonium bicarbonate method produces ammonium sulfite by the reaction of ammonium bicarbonate with sulfur dioxide and water, and then reacts with sulfur heating and boiling after filtering to remove impurities, and then filtration, evaporation, cooling crystallization, and centrifugal separation to obtain ammonium thiosulfate products. That.

2nh4hco3+so2+h2o→(nh4)2so3+2h2o+2co2↑

nh4)2so3+s→(nh4)2s2o

Hurry up"?

First, see how their solubility changes with temperature? Or condensed out?

Second, is it possible to consider adding another sol to extract one of them?

Third, it can be done step by step, not necessarily "once completely separated".

1. Ammonium sulfate chemical formula: (NH4)2SO4.

2. Ammonium sulfate is an inorganic substance, the chemical formula is (NH4)2SO4, colorless crystals or white Qisen grains, odorless. 280 or more decomposed. Solubility in water:

0 hours, 100 hours. Insoluble in ethanol and acetone. The aqueous solution quietly registers the pH of the mu.

Relative density. Refractive index. Ammonium sulfate is mainly used as a fertilizer and is suitable for a variety of soils and crops.

It can also be used in textile, leather, medicine, etc.

3. In industry, ammonia and sulfuric acid are directly neutralized and obtained, and they are not used much, mainly using the by-products or exhaust gas emitted in industrial production to absorb sulfuric acid or ammonia water (such as sulfuric acid absorbing ammonia in coke oven gas, ammonia absorbing sulfur dioxide in the flue gas of smelters, ammonia in the production of Kapulun or sulfuric acid waste liquid in the production of sulfuric acid titanium dioxide). There are also gypsum methods that use gypsum method to produce ammonium sulfate (using natural gypsum or phosphogypsum, ammonia, and carbon dioxide as raw materials).

ls error. Ammonium sulfide in aqueous solution immediately and completely dihydrate.

nh4)2s(aq)=h2s↑+2nh3↑；

It should be combined with dry H2S and NH3 gases to obtain:

2nh3(g)+h2s(g)=(nh4)2s(s).

In the chemistry laboratory, there are three methods to obtain solution crystals according to the different solubility of solution crystals.

First of all, the types of crystal solubility are distinguished: 1. The temperature increases, and the solubility increases. Such as potassium nitrate.

The method of cooling the hot saturation and the solution; 2. When the temperature increases, the solubility is basically unchanged. Such as sodium chloride.

The method of making slippery resistant to evaporation solution; 3. The temperature increases and the solubility decreases. Such as ammonium sulfate, hydroxide to make calcium.

Use the method of heating up.

Note: Evaporation of the solution and heating are two different methods, and the experimental instruments used are different, so the two methods should not be confused.

The functions are: prevent the hydrolysis of ammonia ions and ferrous ions.

If hydrolyzed, a white precipitate (iron hydroxide) will be produced

It can be cooled, and the first thing that comes out is ammonium thiosulfate, but it is not complete.

Or it is the oxidation of ammonium thiosulfate to pass oxygen.

Ammonium sulfate is unstable, with a precipitant.

Ammonium thiosulfate is a chemical substance with the molecular formula (NH4)2S2O3.
