(a) Out of the following pairs, predict with reason which pair will allow greater conduction of electricity : 

(i) Silver wire at 30^{\circ}C or silver wire at 60^{\circ}C.

(ii) 0·1 M CH_{3}COOH solution or 1 M CH_{3}COOH solution.

(iii) KCl solution at 20^{\circ}C or KCl solution at 50^{\circ}C.

(b) Give two points of differences between electrochemical and electrolytic cells

 

 
 
 
 
 

Answers (1)

(a) (i) Silver wire at 30^{\circ}C will allow greater conduction of electricity because as temperature decreases, resistance decreases Hence, conduction increases.

(ii) 0.1 M CH3COOH will allow greater conduction of electricity, because on dilution degree of ionization increases hence conduction increases

(iii) KCl solution at 50^{\circ}C will allow greater conduction of electricity, because at high temperature mobility of ions increases and hence conductance increases

(b)

Electrochemical Cell 

(1) Anode -ve Cathode +ve (2) Convert chemical Energy to electrical energy

Electrolytic Cell

(1) Anode +ve Cathode -ve

(2) Convert electrical Energy to chemical energy
