Question

why cryolite or fluorspar are mixed with pure alumina during electrolysis? ​

Answer 1

Answer:

Cryolite reduces the fusion temperature from 2050 Celsius to 950 Celsius.

Flourspar is used to increase the conductivity of pure alumina as it is almost a non-conductor of electricity

Answer 2

Crolyte or fluorspar is used in the electrolysis process and mixed with alumina  because it helps in increasing the conductivity of alumina and to reduce the fusion temperature which results in the decomposition of the particles when mass electric current is passed through it.

Explanation:

• Electrolysis process requires current and it is necessary that the level of the current should be maintained in order to make the reaction effective.

• In addition to this,fluorspar compound is added to activate the conductivity of the compound so that the electric current will pass through it.
