0.71 g of a sample of bleaching powder `(CaOCl_2)` is dissolved in 100 " mL of " water. 50 " mL of " this solution is titrated with KI solution. The `I_2` so liberated required 10 mL 0.1 M `Na_2S_2O_3` (hypo) solution in acidic medium for complete neutralisation. Calculate the percentage of available `Cl_2` from the sample of bleaching power.
