Question

Standard hydrogen electrode (SHE) is a (A) primary reference electrode (B) secondary reference electrode (C) metal - sparingly soluble salt electrode (D) metal - metal ion electrode

Tardigrade Admin · Accepted Answer

Standard hydrogen electrode (SHE) is primary reference electrode. SHE Is represented by

Pt (s) ∣ H_{2} (g) ∣ H^{+} (a q)

, is assigned a zero potential at all temperatures corresponding to reaction

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

Q. Standard hydrogen electrode (SHE) is a

primary reference electrode

secondary reference electrode

metal - sparingly soluble salt electrode

metal - metal ion electrode

Standard hydrogen electrode (SHE) is primary reference electrode. SHE Is represented by Pt(s)∣H2​(g)∣H+(aq), is assigned a zero potential at all temperatures corresponding to reaction H+aq+e−→21​H2​(g)
