Chapter 19, Problem 19.142SP

Interpretation Introduction

Interpretation:

Metal ion should be identified after the electrolysis of a metal nitrate solution ${\text{M(NO}}_{\text{3}}{\text{)}}_2(aq)$ for $325\min$ with a constant current of $\text{20}\text{.2 A}$ gives $\text{111 g}$ of the metal.

Concept introduction:

During the electrolysis, the amount of substance that is produced at an electrode of cell depends on the amount of charge passed through it. The current can be calculated as follows:

$\mathrm{Charge}(C)=Current(A)\times Time(s)$
