what is the oxidation of ca in caocl2
CaOCl2
it is bleaching powder and its formula is CaoCl2.
chlorine gas
It is CaOCl2 bleaching powder.Its chemical name is calcium oxy chloride
Bleaching powder is calcium hypochlorite. Ca(OCl)2
CaOCl2+ H2O=Ca(OH)2+Cl2
When Bleaching Powder is treated with excess Dil. H2SO4, Cl2 is produced. CaOCl2 + H2SO4 ----> CaSO4 + H2O + Cl2 CaOCl2 + 2HCl --------> CaCl2 + H2O + Cl2 Chlorine gas produced in this way is known as available chlorine.
The oxidation state of chlorine in bleaching powder would be zero.
When CaOCl2 is added to H20 the chlorate ions combine with the water to produce hypoclorous acid and hydroxide ions. The pools pH is subjected to alot of different vaiables the optimum pH for pools is between 7.2-7.8 so to lower pH add HCl or NaHSO4 or to raise pH add Na2CO3 or NaHCO3.
bleaching powder has formula CaOCl2 and it is used for killing the germs present inside the water because it liberates Cl2.
When chlorine is passed through dry slaked lime power Ca(OH)2 , bleaching powder is obtained .Slaked lime --- Ca(OH)2 Chlorine --- Cl2The chemical equn :- Ca(OH)2 + Cl2 ------> CaOCl2 + H2OCaOCl2 is bleaching powderThe three properties Of bleaching powder , (CaOCl2) areIt is a yellowish white powder with a strong smell of chlorineIt reacts with carbon dioxide , dil. HCl and di. H2SO4 to form chlorine gas.It is soluble in water but since it is generally contaminated with Ca(OH)2 , it may produce a milky solution
