AIIMS 2005 Chemistry Galvanic Cells MCQ Question

Type: MCQ-conceptual-Medium-Class 12

The chemical reaction,

2AgCl(s)+H2(g)→2HCl(aq)+2Ag(s)2\text{AgCl}_{(s)} + \text{H}_{2(g)} \rightarrow 2\text{HCl}_{(aq)} + 2\text{Ag}_{(s)}

taking place in a galvanic cell is represented by the notation

A

Pt(s)∣H2(g),1 bar∣1M KCl(aq)∣AgCl(s)∣Ag(s)\text{Pt}_{(s)} \mid \text{H}_{2(g)}, 1\text{ bar} \mid 1\text{M KCl}_{(aq)} \mid \text{AgCl}_{(s)} \mid \text{Ag}_{(s)}

B

Pt(s)∣H2(g),1 bar∣1M HCl(aq)∣1M Ag(aq)+∣Ag(s)\text{Pt}_{(s)} \mid \text{H}_{2(g)}, 1\text{ bar} \mid 1\text{M HCl}_{(aq)} \mid 1\text{M Ag}^+_{(aq)} \mid \text{Ag}_{(s)}

C

Pt(s)∣H2(g),1 bar∣1M HCl(aq)∣AgCl(s)∣Ag(s)\text{Pt}_{(s)} \mid \text{H}_{2(g)}, 1\text{ bar} \mid 1\text{M HCl}_{(aq)} \mid \text{AgCl}_{(s)} \mid \text{Ag}_{(s)}

D

Pt(s)∣H2(g),1 bar∣1M HCl(aq)∣Ag(s)∣AgCl(s)\text{Pt}_{(s)} \mid \text{H}_{2(g)}, 1\text{ bar} \mid 1\text{M HCl}_{(aq)} \mid \text{Ag}_{(s)} \mid \text{AgCl}_{(s)}

Correct Answer

Option B

Detailed Explanation

2AgCl(s) + H2(g) → 2HCl(g) + 2Ag(s)
