Solution
-
In the electrolysis of aqueous lithium chloride, the product formed at the anode is Chlorine. This is because during electrolysis, negative ions migrate towards the anode (which is positively charged) and lose their electrons to become atoms. The chloride ions (Cl-) in lithium chloride will lose their electrons to form chlorine gas.
-
To test whether the gas formed at the anode is a halogen, you can use the method of bleaching damp blue litmus paper. Halogens like chlorine are known for their bleaching properties. If the gas bleaches the blue litmus paper and turns it white, it is a halogen.
-
In the electrolysis of aqueous copper (II) sulfate, Copper is formed at the cathode and Oxygen at the anode. At the cathode, positive ions gain electrons to form atoms. The copper ions (Cu2+) in the solution will gain electrons to form copper atoms. At the anode, negative ions lose electrons to form atoms. The hydroxide ions (OH-) from the water will lose electrons to form oxygen gas and water.
-
In the electrolysis of aqueous sodium chloride, the ions that will be left behind in the solution are Na+ and OH–. This is because the chloride ions (Cl-) will migrate to the anode and be discharged as chlorine gas, and the hydrogen ions (H+) will migrate to the cathode and be discharged as hydrogen gas. The remaining ions in the solution will be Na+ and OH–.
