16 An acid solution of 0 2 mol of KReO was reduce Zn and then titrated with 1 6 Eq of acidic KMnO4 sc For the reoxidation of all the rhenium Re to the per ion ReO4 Assuming that rhenium was the only e reduced what is the oxidate state to which rheniu reduced by Zn a 1 b 2 c 1 d 2 7 A 200 mL solution of I is divided into two L parts Part I reacts with hypo solution in acidic and requires 8 mL of 2 M hypo solution for ce neutralisation Part II was added with 300 mL of 0 1 M NaOH s
