Chapter 19.8, Problem 1CYU

(1)

Interpretation Introduction

Interpretation:

Calculate mass of ${\text{O}}_{\text{2}}$ producedin in  the electrolysis of water.

Concept introduction:

Electrolysis:

It is a decomposition of ionic compounds by passing electricity through molten compounds or aqueous solutions of compounds.

Electricity used to produce chemical changes. The apparatus used for electrolysis is called an electrolytic cell.

Current:

Rate of the charge changing in time is termed as current.

The formula is as follows.

$\text{Current (Amperes, A) = }\frac{\text{Electric charge (Coloumbs, C)}}{\text{time, t(seconds,s)}}$

Simplify as follows.

$\text{Current = }\frac{\text{Electric charge }}{\text{time}}$

To rearrange the above formula is as follows:

$\text{Charge = Current(A) × time(s)}$
