Question

Cu+ is not stable and undergoes disproportionation .Eo for Cu+ disproportionation.....)

$({E^{0}}_{cu^{+ 2}/Cu^{+}} = + 0.153V,{E^{0}}_{Cu^{+}/Cu} = 0.53V)$

• A.
  • 0.683 V
• B.
  • 0. 367
• C.
  • 0. 3415 V
• D.
  • 0.367

Answer 1

Answer: (D)

• 0.367

Answer 2

$2Cu^{+} \rightarrow Cu^{+ 2} + Cu$

${E^{0}}_{cell} = {E^{0}}_{cu^{+}/Cu^{+ 2}} + {E^{0}}_{Cu^{+}/Cu}$

= - 0.153 + 0.53 = + 0.367V
