• # question_answer 73) Explain redox reactions on the basis of electron transfer. Give suitable examples.

Gain of electron is reduction and loss of electron is oxidation. $SnC{{l}_{2}}+HgC{{l}_{2}}\to SnC{{l}_{4}}+Hg$ $S{{n}^{2+}}+H{{g}^{2+}}\to S{{n}^{4+}}+Hg$ $S{{n}^{2+}}\to S{{n}^{4+}}+2{{e}^{-}}$ (loss of electron, i.e., oxidation) $H{{g}^{2+}}+2{{e}^{-}}\to Hg$(gain of electron, i.e., reduction)
