What would be the product of electrolysis if molten ICl3 is electrolysed ?

A

I2 is produced at cathode and Cl2 is produced at anode

B

Cl2 is produced at cathode and I2 is produced at anode

C

Both I2 and Cl2 are liberated at both electrodes

D

ICl2 is produced at cathode and ICl4 is produced at anode

Answer

Both I2 and Cl2 are liberated at both electrodes

Explanation

Solution

In the molten state ICl3 ionises as follows

2ICl3 ICl2+ + ICl4–

Hence both I2 and Cl2 are produced at both the electrodes.
