Question

The electrolysis of acidified water is an example of _______.

• A. reduction
• B. oxidation
• C. redox reaction
• D. synthesis

Answer 1

The correct option is C redox reaction

Acidified water contains ions such as $H^{+},O{H}^{-}$ from dissociation of water and $H^{+},A^{-}$ from the acid $HA$

When current is passed through the cell containing acidified water the $H^{+}$ ions moves to the cathode and get reduce as :

$H^{+}+e^{-}\to HH+H\to H_2\uparrow$

Similarly the anions moves to the anode and upon prefferential oxidation of $O{H}^{-}$ as :

$O{H}^{-}\to OH+e^{-}OH+OH\to H_{2}O+OO+O\to O_2\uparrow$

Therefore it is an example of a redox reaction.

Option C is correct.
