Correct answer: D. Cl ₂ and ClO ^-

Gas X is chlorine ( Cl ₂ ), which is manufactured commercially by Deacon's process. This process involves the oxidation of hydrogen chloride gas by atmospheric oxygen in the presence of a CuCl ₂ catalyst. Chlorine reacts with dry slaked lime ( Ca(OH) ₂ ) to produce bleaching powder. The reaction is: 2 Ca(OH) ₂ + 2 Cl ₂ Ca(OCl) ₂ + CaCl ₂ + 2 H ₂ O The composition of bleaching powder is represented as Ca(OCl) ₂ CaCl ₂ Ca(OH) ₂ 2 H ₂ O . The active bleaching agent in it is the hypochlorite ion ( ClO ^- or OCl ^- ). A
