Question

The cell shown in the image below is used to commercially produce Sr via electrolysis from a molten salt (the electrolyte), such as SrCl₂. Remember that in an electrolytic cell, which is the opposite to what we see in batteries, the anode is given the "-" sign and the cathode is given the "+" sign. What is the half-reaction at the anode of the electrolytic cell?

Accepted Answer

2 Cl^–(aq) → Cl₂(g) + 2e^–

Answer

Sr²⁺(aq) + 2e^– → Sr(l)

Answer

Cl₂(g) + 2e^– → 2 Cl^–(aq)

Answer

Sr(l) → Sr²⁺(aq) + 2e^–
