If an electric current is passed through an electrolyte solution,what happens to the ions?
A
Anions move towards the anode,cations towards the cathode
B
Anions and cations both move towards the anode
C
Anions move towards the cathode,cations towards the anode
D
No movement of ions takes place
Solution
(A) When an electric current is passed through an electrolyte solution,the ions experience an electrostatic force due to the applied potential difference.
Cations (positively charged ions) are attracted towards the cathode (negatively charged electrode).
Anions (negatively charged ions) are attracted towards the anode (positively charged electrode).
Therefore,the correct behavior is that anions move towards the anode and cations move towards the cathode.
Cations (positively charged ions) are attracted towards the cathode (negatively charged electrode).
Anions (negatively charged ions) are attracted towards the anode (positively charged electrode).
Therefore,the correct behavior is that anions move towards the anode and cations move towards the cathode.
