Chapter 19, Problem 112AP

Interpretation Introduction

Interpretation:

The half-cell reaction and overall reaction are to represented; the explanation for what happens to the impurities during the electrolysis is to be given; and the time required to obtain $1.00\text{ kg}$

of Cu is to be calculated.

Concept introduction:

Electrolysis is the process in which electric current is passed through a substance to effect a chemical change. The chemical change in a substance occurs due to loses or gains an electron (oxidation or reduction).

A half reaction is a type of chemical reaction in which either oxidation or reduction takes place as a component of a redox reaction.

The equation for current is represented as charge per unit time. $\text{Current}=\frac{\text{Charge}}{\text{Time}}$
