Question 1 Report

Why is potassium fluoride added to the electrolyte in the extraction of sodium from fused sodium chloride?

Pure sodium chloride does not conduct electricity

Potassium fluoride prevents the sodium produced from attacking the electrodes

Potassium fluride increases conductivity

Potassium fluride reduces the temperature at which sodium chloride fuses

the potassium fluride acts as a catalyst
