The given compound 'A' is calcium oxychloride because it is a oxidising agent and in open it reacts with CO₂ to give pungent smelling chlorine gas.  

CaOCl₂ + CO₂ → CaCO₃ + Cl₂ It is prepared by the action of dry slaked lime with chlorine gas.  

Ca(OH)₂ + Cl₂→  CaOCl₂ + H₂O  

Calcium oxychloride is commercially known as Bleaching powder.
