एक सेल \(Cu ( s ) \mid Cu ^{2+}\left(0.001 M || Ag ^{+}(0.01 M ) \mid Ag ( s )\right.\) के लिए \(298\,K\) पर सेल विभव \(0.43\,V\) पाया गया है। \(Cu ^{2+} / Cu\) के लिए मानक इलेक्ट्रोड विभव का मान \(.......\times 10^{-2}\,V\) है । \(\left[\right.\) Given \(: E _{ Ag ^{\Theta} / Ag }^{\Theta}=0.80 V\) and \(\left.\frac{2.303 RT }{ F }=0.06\,V \right]\)

  1. A \(33\)
  2. B \(32\)
  3. C \(34\)
  4. D \(31\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(34\)

Step-by-step Solution

Detailed explanation

At anode \(Cu \rightarrow Cu ^{2+}+2 e ^{-}\) At cathode \(2 Ag ^{+}+2 e ^{-} \rightarrow 2 Ag\) Cell reaction \(\rightarrow Cu +2 Ag ^{+} \rightarrow Cu ^{2+}+2 Ag\)…
