During electrolysis of brine, a gas ‘G’ is liberated at anode. When this gas ‘G’ is passed through slaked lime, a compound ‘C’ is formed, which is used for disinfecting drinking water.
(i) Write formula of ‘G’ and ‘C’.
(ii) State the chemical equation involved.
(iii) What is common name of compound ‘C’ ? Give its chemical name.
(i) The formula of ‘G’ and ‘C’ are,
G = Cl2 C = CaOCl2
(ii) Chemical equation involved is
Ca(OH)2 + Cl2 → Ca OCl2 + H2O
(iii) The common name of compound C is – Bleaching Powder and its
Chemical name – Calcium Oxychloride
