দাবি: Cu^(2+)(aq) Cu^(2+)(aq) এর চেয়ে বেশি স্থিতিশীল কারণ: ইলেক্ট্রোড সম্ভাবনা বেশি গুরুত্বপূর্ণ...

The reaction Co(s) + Cu^(2+)(aq) rarr Co^(2+)(aq) + Cu(s) is-

E.M.F. of Ni(s) (ni^(2+) (aq)||Cu^(2+) (aq)| Cu(s) cell can be increased by

Cu^(2+)(aq.)+X^(-)(aq.)overset(R.T.)toCuX darr+X_(2) 'X' cannot be:

An electrochemical cell constructed for the reaction : Cu^(2+)(aq) + M(s) rightarrow Cu(s) + M^(2+) (aq) has an E^(@) = 0.75V . The standard reduction potential for Cu^(2+)(aq) is 0.34V. What is the standard reduction potential for M^(2+) (aq)?

The electrode pptenticals for Cu^(2+) (aq) +e^(-) rarr Cu^+ (aq) and Cu^+ (aq) + e^- rarr Cu (s) are + 0.15 V and +0. 50 V repectively. The value of E_(cu^(2+)//Cu)^@ will be.

Assertion: Aquated copper(I) cation undergoes disproportionation as: 2Cu^(+)(aq) to Cu^(2+)(aq)+Cu Reason: Hydration energy of Cu^(2+) is higher than that of Cu^(+) which compensates second ionisation energy of Cu.
