Question

Answer 1

Answer:

Hola..

Here is your answer mate_______☺️

Explanation:

When the hydrated salt (CuSO₄. 5H₂O ) is heated, it loses its water of crystallisation and becomes anhydrous salts (without water of crystallisation). The blue colour of CuSO₄ is due to the presence of water of crystallisation. Hence, when it loses its water of crystallisation, the solution becomes colourless.
