The chemical formula of silver sulphate is AG SO.

Silver sulfate is a white precipitate, slightly soluble in water, soluble in ammonia, nitric acid, slowly soluble in concentrated sulfuric acid, insoluble in ethanol. The reactants that produce silver sulfate, if they are all soluble, are classified as precipitates.

The chemical equation for the decomposition of silver sulphate is 2ag so = 4ag + 2so + o.

Methods for the synthesis of silver sulfate

1. Dissolve silver nitrate in hot water and ammonium sulfate in aqueous solution. After filtration, it is heated and added to the hot silver nitrate solution. After cooling, the silver sulphate crystals are filtered out, then rinsed and dried.

2. Dissolve the pure silver nitrate crystals in a small amount of water, add sulfuric acid (1:2), centrifuge the silver sulfate crystals, transfer them to a platinum dish, dissolve them in hot concentrated sulfuric acid, and boil them to remove any nitric acid that may be present. The crystals are separated by centrifugation and treated with water in a platinum disc.

At this time, on the hot spot, fine powdered silver sulfate crystals are formed.

3. Dissolve silver nitrate with a small amount of distilled water, add more sulfuric acid, that is, to obtain an acidic silver sulfate and acidic mixture solution, heat the solution, evaporate nitric acid, smoke (sulfuric acid begins to decompose into sulfur trioxide), nitric acid is basically discharged, stop heating, add distilled water to the solution, and with the decrease of acidity, silver sulfate precipitates, washes and dries.

The chemical formula of silver sulphate is AG SO.

Silver sulfate is soluble in nitric acid, ammonia and concentrated sulfuric acid, slowly soluble in 125 parts water and 71 parts boiling water, insoluble in ethanol.

It is slightly soluble in pure water, and increases by the decrease of pH of the solution environment, and can have obvious dissolution phenomenon when the concentration of hydrogen ions is large enough.

It is used as an analytical reagent to determine the oxygen consumption of aqueous ashwagandha.

It is used as a catalyst. Determination of nitrite.

vanadate, phosphate and fluorine. Determination of ethylene. It is used as an analytical reagent and a catalyst for the determination of chemical oxygen consumption in water.

It is used as an analytical reagent, such as a catalyst for the determination of chemical oxygen consumption in water. Store in a cool, dry place. Store in an airtight container. Protected from light and stored for protection.

The silver oxide chemical formula is Ag O.

Silver oxide (Agro) is a black solid with a fairly high silver content, and the method used to smelt silver from waste silver oxide is thermal decomposition.

Silver oxide (AGO) coin cell batteries are commonly used in computers and watches, and the reaction in the battery is: Zn+AGo Zno+2AG, and the reducing agent in this reaction is zinc.

The real reason why silver products turn black:

Since ancient times, gold and silver and their manufactured products have been loved. However, radiant silver products will always gradually dim or even darken during use, and their appearance will quickly decrease.

For this phenomenon, many people misunderstand it as the body is detoxifying, and black is the toxin excreted by the body. To debunk the "detoxification" rumors and understand why silver jewelry turns black, let's first take a look at the two forms of silver jewelry turning black:

1. Long-term storage of silverware: the luster is dull, and the surface of the silver is yellow and black.

This is especially common on ancient silverware exhibited in various museums. The black substance on the surface is mainly silver oxide Agro, which is caused by the oxidation of silver when it is exposed to the air for a long time.

Due to the relatively stable chemical properties of silver, it is more difficult to undergo oxidation reactions, so this phenomenon is common in silverware that has been exposed to the air for a long time. The corners and sharps of silverware are more susceptible to oxidation due to their higher energy.

2. Silver jewelry is worn close to the body: it is getting darker and darker, and the body is close to the black block.

This kind of situation is more common in our clan reforms: most silver jewelry, such as silver rings and bracelets, will lose their luster and even develop black patches after wearing them for months or even weeks.

Silver thiosulfate bai is a white crystal.

DU body. Slightly soluble in water, soluble in sodium thiosulfate dissolved in DAO solution.

In case of acid, it is decomposed into oxidized inner silver, sulfur dioxide and sulfur.

Add a small amount of silver nitrate dropwise to sodium thiosulfate and shake it, and the resulting precipitate disappears immediately. This is due to the formation of a complex of silver thiosulfate and sodium thiosulfate produced

Na2S2O3+2AgnO3==2nano3+Ag2S2O3 Ag2S2O3+2Na2S2O3==A2Na4(S2O3)3 (This is a soluble substance).
