Question

Explain faraday's first law of electrolysis in details.

Answer 1

Faraday's First law of electrolysis

• Michael Faraday established Faraday's law of electrolysis.
• According to Faraday's First Law of Electrolysis, the chemical deposition caused by the flow of current through an electrolyte is proportionate to the amount of electricity passing through it.
• The amount of electricity needed to release one gram-equivalent of any material at any electrode is called a faraday, and it passes through an electrolyte.
• Faraday's constant is equal to $96485\mathrm{C}{\mathrm{mol}}^{-1}$.

Formula of Faraday's first law

$$\begin{gathered} m\propto Q \\ m=ZQ \\ m=ZIt \end{gathered}$$

• $m$ is the mass of the ions formed or reacted.
• $Q$ is the electric current.
• $Z$ is the electrochemical equivalent mass of one-coulomb charge.
• is the current.
• is the time
• When one coulomb equals one electrochemical equivalent mass of a material, one equivalent of electrons flowing per second equals $96485$ equivalents mass.
