Consider the figure given alongside and answer the questions (i) to (vi) given below (i) Give the direction of electron flow. (ii) Is silver plate the anode or cathode ? (iii) What will happen if salt bridge is removed ? (iv) When will the cell stop functioning ? Zinc plate ,, (v) How will concentration of Zn^(2+) ions and Ag^(+) ions be affected when the cell functions ? (vi) How will the concentration of Zn^(2+) ions and Ag^(+) ions be affected after the cell becomes 'dead' ?

Answer»

Solution : (i) Electrons move from Zn to Ag.
(ii) Ag is the cathode.
(iii) CELL will stop functioning.
(iv) When `E_("cell")=0`
(v) Concentration of `Zn^(2+)` ions will increase and concentration of `Ag^(+)` ions will DECREASE.
(vi) When `E_("cell")=0` equilibrium is reached and concentration of `Zn^(2+)` ions and `Ag^(+)` ions will not change.
