Q. Write balanced chemical equations for the reactions taking place when dry crystals of copper sulphate are dropped into conc. sulphuric acid. [1 mark question]
(please give a detailed answer with the board marking scheme)
Concentrated sulphuric acid is a strong dehydrated agent. It takes out the water of crystallization from the crystals of copper sulphate leaving behind an anhydrous white powder of Cu2SO4.
Cu2SO4.5H2O ------> Cu2SO4 + 5H2O
