A solution of blue vitriol is acidic in nature because :(a) CuSO4 reacts with water (b) Cu2+ ions reacts with water (c) \(SO_4^{2-}\) ions reacts with water (d) CuSO4 removes OH- ions from water |

Answer» (A) \(CuSO_4\) reacts with water Blue vitriot \((CuSO_4\,5H_2O)\) in water is acidic because when \(CuSO_4\) dissolves in water, it forms aqueous solution of strong acid (\(H_2SO_4\)) and weak base (\(Cu(OH)_2\)). \(CuSO_4+2H_2O\longrightarrow Cu(OH)_2+H_2SO_4\) \(Cu(OH)_2\) remains in equilibrium but \(H_2SO_4\) fully ionises to give \(H^+\) ions Therefore, solution of \(CuSO_4\) is acidic in nature. Option : (a) CuSO4 reacts with water. |
