Question

Can we use a copper vessel to store MAgNO3 solution? Given E–Ag+/Ag = 0.80V.

Solution

Dear Student,

If we store AgNO₃ solution in a copper vessel the copper will be oxidized and forms Cu(NO₃)₂ and silver gets reduced to silver metal and hence the copper vessel gets corroded.

$2 A g N O_{3} (a q) + C u (s) \to C u (N O_{3})_{2} (a q) + 2 A g (s)$

This happens because copper is more reactive than silver and hence oxidises itself and reduces Ag⁺ ions to Ag. [E^oCu²⁺/Cu = +0.34 V].
