A solution of 0.1M KMnO_4is used for the reaction S_(2)O_(3)^(-2) + 2

1.	A solution of 0.1M KMnO_4is used for the reaction S_(2)O_(3)^(-2) + 2 MnO_(4)^(-) + H_(2)OrarrMnO_(2) +SO_(4)^(2-)+ OH^(-) . The volume of KMnO_4required to react 0.158gm of Na,s,o, is (MW = 158)
Answer» 13.33 ML 6.66 ml 3.33 ml 26.67 ml Solution :No. of MILLI equivalents of `KMnO_4` = No of milli equivalents of THIOSULPHATE ions `V xx0.1 xx3=(0.158)/(((158)/8))xx1000` `V = 80/3 =26.67 ml`
