Question

what is faradays first laww??​

Answer 1

$\color{red}\underline{\sf Micheal Faraday -}$

He was the first scientist who described the quantitative aspects of electrolysis.

$\color{darkblue}\underline{\underline{\sf Faraday\:First\:Law-}}$

The Amount of chemical reaction which occurs at any electrode during electrolysis by a current is proportional to the quantity of electricity passed through the electrolyte

It is given as -

$\color{violet}\bullet\boxed{\sf m \: \: \propto\:\:Q}$

$\implies{\sf m\:\:\propto\:\:it}$

i = Current

t = time

$\color{violet}\bullet\boxed{\sf m = Zit}$

Z = Electro chemical equivalent ( ECG )

If in any cell 1 A current flow for 1sec then mass deposit at cathode called $\color{red}{\sf Electro\: Chemical\: Equivalent}$

$\color{violet}\bullet\boxed{\sf Z=\dfrac{m}{it}}$

Unit $\implies{\sf \dfrac{kg}{Amp×sec}}$

When "it" is same

$\Large\color{violet}\bullet\boxed{\sf \dfrac{m_1}{m_2}=\dfrac{Z_1}{Z_2}}$
