Why blue colour of `CuSO_(4)` solution gets discharged when zinc rod is dipped in it ? Given, `E_(Cu^(+2)//Cu)^(@)=0.34 V and E_(Zn^(+2)//Zn)^(@)=-0.76V`

For the given cell arrangement identify incorrect statement given E^@_(Cu^(2+)//Cu) = 0.34V & E^@_(Zn^(2+)//Zn) = -0.76V

For the given cell arrangement identify incorrect statement given E^@_(Cu^(2+)//Cu) = 0.34V & E^@_(Zn^(2+)//Zn) = -0.76V

The standard cell potential for the cell Zn|Zn^(2+) (1 M)|| Cu^(2+) (1 M)| Cu Given E_(Cu^(2+)//Cu)^(@) = 0.34 V and E_(Zn^(2+)//Zn)^(@) = - 0.76 V is

Which among the following vessels is used to store CuSO_(4) solution ? a Zn vessel [ Given E_(Zn^(2+)|Zn)^(@)=-0.76V, E_(Cu^(2+)|Cu)^(@)=+0.34V and E_(Ag^(+)|Ag)^(0)=0.80V ]
