Question

CuSO4 was prepared by reacting an acid and a base. Identify the acid and the base that must have been used in this reaction.

Answer 1

acid : H2SO4 (Sulphuric acid)

base : Cu(OH)2 (Copper hydroxide)

Answer 2

CuSO4 is a salt formed when combining Cu(OH)2 and H2SO4

Explanation:

Sulfuric acid and Cupric hydroxide  react to form Cupric sulphate and water.

Sulfuric acid is a colorless, odorless liquid.

Cupric hydroxide is a blue or blue-green solid.

Copper sulphate is a beautiful blue coloured salt.

The balanced equation of this reaction is:

Cu(OH)2 + H2SO4 --> CuSO4 + 2 H2O.
