Consider the reactions
`H_(3)PO_(2)(aq)+2CuSO_(4)(aq)+2H_(2)O(l)toH_(3)PO_(4)(aq)+2Cu(s)+H_(2)SO_(4)(aq)`
What interference do you draw about the behaviour of `Ag^+` & `Cu^(2+)` from these reactions?

Text Solution

Verified by Experts

The reaction involves the reduction of `CU^(2+)` ion to Ag and the oxidation of `H_(3)PO_(2)`to `H_(3)PO_(4)` .Thus in this reaction `Cu^(2+)` ion behaves as an oxidant. It oxidises `H_(3)PO_(2)`toH_(3)PO_(4)`
