Hint: Electrolysis is the process by which a chemical compound infused state or in aqueous solution undergoes a chemical change on the passage of current. It comprises two tubes, one cathode and another anode.
Complete answer:
According to Faraday's first law of electricity, “whenever the current is allowed to pass through an electrolytic chamber, then the chemical deposition of the electrolyte will be directly proportional to the quantity of electricity passed through the solution.”
The weight or the mass of deposition of the electrolyte is directly proportional to the amount of electricity passed through the solution.
Mathematically,
${ w\propto q }$
Thus, ${ w=Z\times q }$
${ w=Z\times I\times t }$
where w = amount of electrolyte deposited
Z = constant of proportionality called the electrochemical equivalent of the substance.
q = amount of charge passed in the circuit.
I = current
t = time
Additional Information: The number of electrons accepted by an anode is equal to the number of electrons donated by the cathode.
The preferential discharge of ions depends upon their position in the electrochemical series and the concentration of ions.
Neutral atoms of metals and hydrogen are liberated at the cathode. Therefore, they are called electropositive elements. Neutral atoms of non-metals are liberated at the anode. Therefore, they are called electronegative elements.
Note: The possibility to make a mistake is that the first law is based on quantitative relationships based on electrochemical research, not qualitative relationships. Also, on passing the electric current, cations migrate towards the cathode while the anions migrate towards the anode.
