Between `Cu_((aq))^(2+) and Cu_((aq))^(+)` which is more stable?

Cu_(2)Cl_(2) and CuCl_(2) in aqueous mdeium

Predict whether the reaction 2Ag_((s))+Zn_((aq))^(2+)rarr 2Ag_((aq))^(+)+Zn_((s)) is feasible or not.

a) For the electrochemical cell represented as: Cu_((s))|Cu_((aq))^(2+)||Ag_((aq))^(+)|Ag_((s)) , write the half cell reaction that occurs at (i) anode (ii) cathode

Which one of the following condition will increase the voltage of the cell represented by the equation : Cu_((s))+2Ag_((aq))^(+)hArr Cu_((aq))^(+)+2Ag_((s))

For a given data : E_(Mg^(2+) // Mg)^(@) = -2.37 V , E_(Cu^(2+)// Cu)^(@) = + 0.34 V Calculate the emf of the cell in which the following reaction takes place . underset((0.0001 M)) ( Mg_((s))) + Cu_((aq))^(2+) underset((0.001M)) to Mg_((aq))^(2+) + Cu_((s))

The emf of the half cell Cu_((aq))^(2+)//Cu_((s)) containing "0.01 M Cu"^(2+) solution is +0.301 V . Calculate the standard emf of the half cell.

Give reasons: i) Cu^(+2) (aq) is more stable than Cu^(+) ii) Ionisation enthalpy increases along transition elements from left to right iii) Zn has highest value for E^(@)(M^(3+)//M^(2+)) among 3d series elements
