Answer:
Step-by-step explanation:
Aqueous solution of copper sulphate
is acidic in nature, as when copper sulphate on dissolving with water, following chemical reaction takes place :
CuSO4 + 2 H2O ====> Cu(OH)2 + H2 SO4
As we can see, copper hydroxide and sulphuric acid is generated in this chemical reaction.Copper hydroxide is a weak base whereas sulphuric acid is a very strong acid which results into increase in acidity of the solution.
Thus, the aqueous solution of copper sulphate is acidic in nature.
