Chapter 18, Problem 114AE

(a)

Interpretation Introduction

Interpretation:

The current required to produce 5.52 kg of Ca when molten CaCl₂ is electrolyzed for 8.00 h needs to be calculated

Concept Introduction:

Electrolysis is a process in which electric current is passed through a molten or aqueous solution of a certain electrolyte in order to bring out a desired chemical change.

The current (I) passed through the solution is related to the charge (Q) and the time (t) as:

  $\text{I (Amperes)=}\frac{\text{Q (coulombs)}}{\text{t (time in seconds)}}\text{ ---(1)}$

  $$
