It is necessary to add H2S04 so that the hydrolysis can be prevented.
Explanation:
- The crystallization of copper sulfate is done by adding water and a little H2So4 in it.
- The H2SO4 prevents the hydrolysis of the copper sulfate crystals being formed.
- Without H2SO4, hydrolysis might occur and the desired crystals might not be formed. Without H2SO4, the CuSO4 is converted into copper sulfate pentahydrate.
- The copper sulfate crystals when formed correctly are blue or violet in color.
