Question

Standard hydrogen electrode $(SHE)$ is a

primary reference electrode

secondary reference electrode

metal - sparingly soluble salt electrode

metal - metal ion electrode

Answer

primary reference electrode

Explanation

Solution

Standard hydrogen electrode (SHE) is primary reference electrode. SHE Is represented by $Pt ( s )\left| H _{2}(g)\right| H ^{+}(a q)$ , is assigned a zero potential at all temperatures corresponding to reaction

$H^{+}aq +e^{-} \to \frac{1}{2} H_{2}(g)$
