Question

The dependence of electrode potential for the electrode $M^{n+}\to M$ with concentration under STP conditions is given by the expression:

• A. $E=E^{⊝}-\frac{0.0591}{n}lo{g}_{10}\left[M^{n+}\right]$
• B. $E=E^{⊝}+\frac{0.0591}{n}lo{g}_e\left[M^{n+}\right]$
• C. $E=E^{⊝}-\frac{0.0591}{n}lo{g}_e\left[M^{n+}\right]$
• D. $E=E^{⊝}+\frac{0.0591}{n}log10\left[M^{n+}\right]$

Answer 1

The correct option is D $E=E^{⊝}+\frac{0.0591}{n}log10\left[M^{n+}\right]$

$E=E^{⊝}-\frac{0.0591}{n}log\frac{1}{\left[M^{n+}\right]}$
$=E^{⊝}+\frac{0.0591}{n}\left[M^{+n}\right]$
