Can simple distillation be done to separate water from aqueous magnesium sulphate?

Description : Can simple distillation be done to separate water from aqueous magnesium sulphate?

Last Answer : Yes.Because simple distillation is a separating of a mixturethrough heating.it is only applied to separate volatile liquid fromthe nonvolatile ones.The gas created by the distillation iscollected through condensation to form a liquid again.Thank you'_'

Electrolysis of an aqueous solution of copper sulphate using copper electrodes gives (1) Copper at eathode and oxygen at anode. (2) Copper at anode and oxygen at cathode. (3) Copper at cathode and anodes dissolve to give copper. (4) Hydrogen at cathode and oxygen at anode.

Description : Electrolysis of an aqueous solution of copper sulphate using copper electrodes gives (1) Copper at eathode and oxygen at anode. (2) Copper at anode and oxygen at cathode. (3) Copper at cathode and anodes dissolve to give copper. (4) Hydrogen at cathode and oxygen at anode.

Last Answer : (1) Copper at eathode and oxygen at anode. Explanation: Copper is deposited at the cathode and is dissolved at the anode. Consequently the concentration of copper ions in solution remains constant. This can be used as a method of purification of copper as only pure copper is deposited at the cathode
