Brine- salty water
Electrolysis of brine
When a salt (e.g. lead bromide ) is molten it will conduct electricity.
Brine is a solution of sodium chloride in water. The solution contains sodium ions, Na+(aq), chloride ions, Cl- (aq), hydrogen ions, H+ (aq), and hydroxide ions, OH-(aq).
When the brine is electrolysed hydrogen is produced at the negative electrode from the hydrogen ions. Chlorine is produced at the positive electrode from the chloride ions.
This will then leave a solution of sodium ions and hydroxide ions, NaOH(aq)
