Copper sulfate pentahydrate Introduction

Copper sulfate pentahydrate (chemical formula: CuSO4 5H2O) is blue alum, bile alum, blue triclinic crystal, easy to weather in dry air, lose 4 molecules of crystal water when heated to 190°C, and become anhydrous salt at 258°C. poisonous. Soluble in water, insoluble in ethanol. It can be used in pesticides, harmful if swallowed, irritating eyes and skin, and can have long-term adverse effects on the chemicalbook water environment. Copper sulfate crystal is a beautiful blue crystal. Its crystal is plate-shaped or short columnar, with a beautiful blue color. The main component is copper sulfate pentahydrate, that is, the hydrate of copper sulfate, which can be used for electroplating or dyeing In dry air, it will become opaque light green white powder due to loss of water.

Chemical properties

Copper sulfate pentahydrate is very stable at normal temperature and pressure, does not deliquesce, and will gradually weather in dry air. When heated to 45°C, it loses two molecules of crystallization water, and loses four molecules of crystallization water at 110°C. It is called copper sulfate monohydrate. At 200°C, it loses all crystal water and becomes anhydrous. It can also lose five crystal waters under the action of concentrated sulfuric acid. Anhydrous is also easy to absorb water and transform into hydrated copper sulfate. After absorbing water, it reacts to produce copper sulfate pentahydrate (blue), which is often used to test whether some liquid organic substances contain trace moisture (for example, to identify whether the alcohol contains water, add a little anhydrous copper sulfate to the alcohol to be identified, If the white anhydrous copper sulfate turns blue, it means that the alcohol is mixed with water).
