Following reactions occur at cathode during electrolysis of aqueous silver chloride solution :
`Ag^(+)(aq)+e^(-) to Ag(s),E^(@)=+0.80" V"`
`H^(+)(aq)+e^(-) to 1//2 H_(2)(g), E^(@)=0.00" V"`
On the basis of standard reduction potential (`E^(@)` value), which reaction is feasible at cathode and why ?

Text Solution

Verified by Experts

The species that get reduced at cathode is that one having higher value of standard reduction potential. Hence, the reaction that will occur at cathode is
`Ag_(aq)^(+) + e^(-)rightarrow Ag_(s)`.

Following reactions occur at cathode during the electrolysis of aqueous copper (II) chloride solution: CU_((aq))^(2+)+ 2e^(-)rightarrow Cu_(s), E^(@) = + 0.34V H_((aq))^(+) +e^(-) rightarrow (1)/(2)H_(2(s)), E^(@) = 0.00V On the basis of their standard reduction electrode potential (E^(@)) values, which reaction is feasible at the cathode and why?

Ag^(+)(aq) + e^(-) rightarrow Ag(s) E^(@) = 0.80V Co^(2+)(aq) + 2e(-) rightarrow Co(s) E^(@) = -0.28V Use the standard reduction potentials to determine the standard potential for the reaction: Co(s) + 2Ag^(+)(aq_) rightarrow Co^(2+)(aq) + 2Ag(s)

Consider a voltaic cell based on these half - cell reactions Ag^(+)(aq)+e^(-)rarrAg(s): E^(@)=+0.80V Cd^(+2)(aq)+2e^(-)rarrCd(s), E^(@)=-0.40V identify the anode and give the voltage of this cell under standard condition.
