Question

Answer the following question with respect by hydrogen : Identify the components of the electrolyte other than pure alumina and the role played by each.

Answer 1

 Components of electrolyte: Cryolite and fluorspar 
Role played by each electrolyte is given below:

1. Cryolite lowers the fusion temperature from 2050°C to 950°C and enhances conductivity.
2. Fluorspar andcryolite act as a solvent for the electrolytic mixture and increase conductivity.
