Redox Reactions · Iodometric redox titration
500 mL of 0.2 M solution in basic medium when mixed with 500 mL of 1.5 M KI solution, oxidises iodide ions to liberate molecular iodine. This liberated iodine is then titrated with a standard M thiosulphate solution in presence of starch till the end point. If 300 mL of thiosulphate was consumed, then the value of is .
