chemical property

Hydration reaction: Anhydrous copper sulfate undergoes a hydration reaction when it comes into contact with water, quickly turning blue and producing blue pentahydrate copper sulfate. This characteristic is commonly used to test the presence of water.

Hydrolysis reaction: It belongs to strong acid weak base salts, and after hydrolysis in aqueous solution, it will show weak acidity.

Reaction with alkali: Adding strong alkali such as sodium hydroxide to copper sulfate solution will result in a light blue-green precipitate of copper hydroxide.

Reaction with metals: According to the metal activity sequence table, metals with activity before metals can participate in the displacement reaction of copper sulfate.

Guizhong reaction: As copper is a variable valence metal, copper sulfate can also participate in the Guizhong reaction.

purpose

Analytical reagent: Used as a solution for preparing Ficin reagent for identifying reducing sugars and biuret reagent for identifying proteins in biology.

In the agricultural field, Bordeaux mixture is produced by mixing with lime water as a fungicide, used to control fungi on crops and prevent fruit decay.
