Write the reaction equation: CuSO4 → Cu (OH) 2 → CuCl2 → Cu (NO3) 2

In this task, you need to write down the reaction equations for the next chain of compounds. It turns out the following.

CuSO4 → Cu (OH) 2 → CuCl2 → Cu (NO3) 2.

1. Reaction of exchange.

CuSO4 + 2NaOH = Na2SO4 + Cu (OH) 2.

When copper sulfate and sodium hydroxide react, the result is sodium sulfate and copper hydroxide.

2. Reaction of exchange.

Cu (OH) 2 + 2HCl = CuCl2 + 2H2O.

The interaction of copper hydroxide and hydrochloric acid results in the formation of copper chloride and water.

3. СuCl2 + 2AgNO3 = Cu (NO3) 2 + 2AgCl.

An exchange reaction with the formation of a precipitate of silver chloride.
