Answer 2

In the case of the quinhydrone electrode, the redox reaction is between quinone as oxidant and hydroquinone as reductant.

Explanation:

• Quinhydrone electrode is used to measure the hydrogen ion concentration (pH) of a solution containing an acidic substance.
• It is an electrode  which consists of a platinum wire dipped in a solution containing quinhydrone which is used to determine hydrogen-ion concentration.
• A platinum electrode is dipped in saturated solution of quinhydrone
• $C 6H 6O 2 ------ H 4O 2 + 2H+ +2e-$
• Through these electrode pH determination can be done and the tempertaure in the half cell is maintained.
