Answer 2

Answer:

The formula C6H402. C6H4 (OH) 2 is Quinhydrone

Explanation:

• The Quinhydrone Electrode ( Pt/Q, H2Q)
• C6H4O2 . C6H4 (OH)2 ↔ C6H4O2 + C6H4 (OH)
• The molecular formula C6H4(OH)2 (molar mass: 110.112 g/mol) may refer to: Catechol, or pyrocatechol. Hydroquinone, also known as benzene-1,4-diol or quinol.

• The oxidizer is hydrogen peroxide, which oxidizes hydroquinone (C6H4(OH)2) to quinone C6H4O2.
• Actually, in hydroquinone, the carbon atoms where -OH groups are linked pass from an oxidation state of +1 to +2 in quinone.
• Obviously, the reducer is hydroquinone, which reduces the oxygen atoms of hydrogen peroxide from -1 to -2.
