Text solutionVerified

When electric current is passed through an electrolyte in its molten or aqueous state, the electrolyte breaks up into its constituent ions.
When aqueous

K Cl

undergoes electrolysis, the ions

K^{+}

and

C l^{-}

are formed where potassium transfers its one valence electron to Chlorine. So potassium becomes positively charged and chlorine becomes negatively charged.
When aqueous

M g C l_{2}

undergoes electrolysis, the ions

M g^{2 +}

and two

C l^{-}

ions are formed where magnesium transfers its two valence electron to chlorine. Thus magnesium gets two positive charges and each chlorine gets one negative charge.
