electrolysis of aluminium sulphate

Electrolysis of aluminum in a solution of magnesium ...

2019-12-28  Show activity on this post. Magnesium sulfate ionizes to Mg++ and SO4-- ions in water. When current is passed thru a solution of these ions, sulfate ion will be electrolyzed at the anode, giving O2 and SO3 which becomes H2SO4. The pH at the anode will decrease as acid is produced and attacks the aluminum. A thick layer may build up.
