Question

How does pH Affect Redox Potential?

Answer 1

Redox Potential: It represents the tendency of a chemical substance to lose or gain electrons. With the help of redox potential, we get to know, whether the substance will undergo oxidation or reduction.

$\mathrm{pH}$ affecting redox potential as

Increasing the value of $\mathrm{pH}$ will decrease the redox potential. When the concentration of ${\mathrm{H}}^{+}$ rises, the solution becomes acidic, and the $\mathrm{pH}$ rises, lowering the redox potential.

Therefore, as the $\mathrm{pH}$ increases, the redox potential will decrease.
