Predict the species that will be reduced first if a mixture of molten salts containing the following ions undergoes electrolysis: Na⁺, Ca²⁺, Cl⁻, Br⁻, F⁻

Question

Quizplus · Accepted Answer

During electrolysis, cations are attracted to the cathode, where they are reduced. Na⁺ has a lower reduction potential than Ca²⁺, so it will be reduced first. Cl⁻, Br⁻, and F⁻ are anions and will not be reduced during electrolysis.
