Problem

P is produced by the action of chlorine on dry slaked lime. Q is a non-corrosive base and used for faster cooking. On heating R at 373 K, it becomes calcium sulphate hemihydrate. Identify P, Q and R respectively. (A) CaOCl2CaOCl_2, NaHCO3NaHCO_3, CaSO4⋅2H2OCaSO_4\cdot 2H_2O (B) CaOCaO, Na2CO3Na_2CO_3, CaOCl2CaOCl_2 (C) Ca(OH)2Ca(OH)_2, NaHCO3NaHCO_3, CaSO4CaSO_4 (D) CaOCl2CaOCl_2, Na2CO3Na_2CO_3, NH4ClNH_4Cl
