Chemical equivalent

Vedclass · Answer

(C) According to Faraday's second law of electrolysis,the mass of different substances deposited by the same quantity of electricity are proportional to their chemical equivalents $(E)$.Since $m = Z \cdot I \cdot t$,and $Q = I \cdot t$ is constant,we have $Z \propto E$.Therefore,$\frac{Z_{	ext{element}}}{Z_{	ext{hydrogen}}} = \frac{E_{	ext{element}}}{E_{	ext{hydrogen}}}$.Since $E_{	ext{hydrogen}} = 1$,we get $Z_{	ext{element}} = Z_{	ext{hydrogen}} 	imes E_{	ext{element}}$.Thus,the electrochemical equivalent of any element is the product of the electrochemical equivalent of hydrogen and its chemical equivalent.

The electrochemical equivalent $Z$ of any element can be obtained by multiplying the electrochemical equivalent of hydrogen with
