Introduction:
Silver sulfate Introduction:
Silver sulfate is a kind of sulfate, chemical formula Ag2SO4, soluble in nitric acid, ammonia and concentrated sulfuric acid, insoluble in ethanol, slightly soluble in water, and increased by the decrease of the pH of the solution environment, when the concentration of hydrogen ions is large enough to have obvious dissolution phenomenon. Used as an analytical reagent, used as a catalyst in the determination of chemical oxygen consumption in water.
Silver sulfate Usage：
1. Silver sulfate is used for colorimetric determination of nitrite, vanadate, phosphate and fluorine. Determination of ethylene and determination of cobalt and chromium in water quality analysis.
2. Silver sulfate is used as an analytical reagent, such as a catalyst when determining chemical oxygen consumption in water.
