If sodium sulphate is considered to be completely dissociated into cations and anions in aqueous solution,the change in freezing point of water(ΔTf),when 0.01 mole of sodium sulphate is dissoved in 1 kg of water,is ( Kf = 1.86 K kg mol−1) If sodium sulphate is considered to be completely dissociated into cations and anions in [...]
