What ions are in sodium chloride solution?

Sodium chloride solution contains sodium ions (Na +), chloride ions (Cl –), hydrogen ions (H +) and hydroxide ions (OH –). During electrolysis, the Cl – move towards the positive electrode where they are oxidised to form chlorine atoms (Cl).

Can sodium chloride be electrolysed?

Sodium chloride in solution can be electrolysed to produce chlorine gas, hydrogen gas and sodium hydroxide solution, as shown by the diagram below. Sodium chloride solution contains sodium ions (Na +), chloride ions (Cl –), hydrogen ions (H +) and hydroxide ions (OH –).

Which element is produced by electrolysis of sodium chloride solution?

However, the electrolysis of sodium chloride solution produces hydrogen. Note that the electrolysis of sodium chloride solution produces chlorine gas and hydrogen gas but also leaves a solution of sodium hydroxide as well. If the negative ion from the ionic compound is simple (eg Cl – or Br –), then that element is produced.

What happens during electrolysis of sodium chloride solution?

As shown above, the electrolysis of sodium chloride solution will produce chlorine gas at the anode and hydrogen gas at the cathode. oxidation The gain of oxygen, or loss of electrons, by a substance during a chemical reaction. reduction The loss of oxygen, gain of electrons, or gain of hydrogen by a substance during a chemical reaction.

How does a sodium chloride solution conduct electricity?

I know that sodium chloride dissociates into sodium and chloride ions in water, so when a voltage is applied, those ions can move.

Why is sodium hydroxide formed during the electrolysis of sodium chloride solution?

During the electrolysis, hydrogen and chloride ions are removed from solution whereas sodium and hydroxide ions are left behind in solution. This means that sodium hydroxide is also formed during the electrolysis of sodium chloride solution.
