Chapter 19, Problem 19.116QP

Interpretation Introduction

Interpretation:

The grams mass of Lactic acid present in given sample should be calculated.

Concept introduction:

Faraday's first law:

The amount of substance, which is liberated from electrolysis, is directly proportional to the amount of current passed through an electrode.

$\begin{array}{l}\text{M α Q}\\ \text{Mass α charge}\\ \text{M α It g}\end{array}$

$\begin{array}{l}\text{I= current in amperes }\\ \text{t = time in seconds }\\ \text{M= produced mass in grams}\text{.}\end{array}$
