Consider a Galvenic cell,
`Zn(s) |Zn^(2+) (0.1M) ||Cu^(2+) (0.1M)|Cu(s)`
by what factor, the electrolyte in anodic half cell should be diluted to increase the emf by 9 mili volt at 298K`.

For the cell Zn(s)|Zn^(2+) (2M)||Cu^(2+) (0.5 M)|Cu(s) (a) Write equation for each half reaction. (b) Calculate the cell potential at 25^@C

What will happen to the value of emf of the cell Zn|Zn^(2+)(0.1M)||Cu^(2+)(0.1 M)|Cu , if the concentration of the electrolyte in the anode compartment is increased?

If at 25^@C , the standard emf of the cell |Zn(s)| Zn^2+ (1M) || Cu^2(0.1 M) | Cu (s) is 1.3 volt, calculate the emf of the cell.

For the cell reaction Zn(s) +Cu^(2+)(0.1M) rarr zn^(2+)(0.01M) + Cu(s) , If E^(@) is the strandard e.m.f. of the cell, then

For a standard cell Zn(s)|Zn^(2+)(1 M)||Cu^(2+)(1 M)|Cu(s) Write the electrode reaction and cell reaction. Also find the e.m.f. of cell if ? E_(Zn^(2+)|Zn)^(@)=-0.76" V", E_(Cu^(2+)|Cu)^(@)=+0.34" V" .

Consider the cell Zn|Zn^(2+) || Cu^(2+)|Cu. If the concentration of Zn and Cu ions are doubled, the emf of the cell.
