Question

1 $0 \mathrm{~L}$ each of a buffer containing $1 \mathrm{~mole} \mathrm{NH}_{3}$ and $1 \mathrm{~mol}$ of $\mathrm{NH}_{4}^{+}$ were placed in the cathodic and anodic half-cells and $965 \mathrm{C}$ of electricity was passed. If anodic and cathodic half cells reactions involve oxidation and reduction of water only as
$2 \mathrm{H}_{2} \mathrm{O} \longrightarrow 4 \mathrm{H}^{+}+\mathrm{O}_{2}-4 \mathrm{e}^{-}$
$2 \mathrm{H}_{2} \mathrm{O}+2 \mathrm{e}^{-} \longrightarrow \mathrm{H}_{2}+2 \mathrm{OH}^{-}$
Then $\mathrm{pH}$ of

Aicharya · Accepted Answer

Due to buffer action the $\mathrm{pH}$ will remain practically constant. ,
