0.5 g bleaching powder was suspended in water and excess KI is added. On acidifying with dil. H_(2)SO_(4), I_(2) was liberated which required 50 mL of N//10 hypo (Na_(2)S_(2)O_(3). 5H_(2)O) in presence of starch. The reactions involved are : I. CaOCl_(2)+H_(2)SO_(4) to CaSO_(4) to CaSO_(4)+H_(2)O +Cl_(2) II. 2KI+Cl_(2) to 2KCl+I_(2) III. 2Na_(2)S_(2)O_(3)+I_(2) to Na_(2)S_(4)O_(6)+2NaI Starch forms iodo-starch complex in the given titration. The colour of the complex will be :
