1.	What is bleaching powder? Give equation for its reaction with(1) HCl (2) CO2 (3)H2So4
Answer» \xa0(a) Bleaching powder is Calcium oxychloride (CaOCl2\u200b). It is prepared by passing chlorine gas over dry slaked lime.\xa0Reaction:\xa0Ca(OH)2\u200b+Cl2\u200b→CaOCl2\u200b+H2\u200bO\xa0(b) When bleaching powder reacts with dilute sulphuric acid, it produces chlorine gas.\xa0Reaction:\xa0CaOCl2\u200b+H2\u200bSO4\u200b→CaSO4\u200b+Cl2\u200b(g)+H2\u200bO(l)\xa0(c) Two important uses of bleaching powder are-\xa0 (i) It is used for disinfecting the drinking water supply.\xa0 (ii) It is used in the manufacture of chloroform.
