Question

Calculate the mass of mg during electrolysis of molten mgcl2 using 0.5 amp current which is passed for 1.5 hours

Answer 1

Answer:

MgCl2 has to be heated until molten in order for it to conduct electricity. When molten you have Mg2+ and 2Cl- ions. Then electrolysis separates the elements. The Mg2+ is reduced at the cathode (-) and the Cl- is oxidized at the anode (+).
