Problem: Magnesium, the element, is produced commercially by electrolysis from a molten salt (the "electrolyte") using a cell similar to the one shown below.Chlorine gas is evolved as voltage is applied in the cell. Knowing this, identify the electrolyte.

We are asked to determine the electrolyte present in the following:

A diagram shows a box containing electrolyte with two electrodes in it, one steel and one carbon.  The negative end of a voltage source is attached to the steel electrode while the positive end is attached to the carbon electrode.  There is a thin layer of liquid Mg near the steel electrode.  Bubbles from around the carbon electrode are Cl2 (gas), which escapes through an outflow tube.
