Explain, using structure and bonding, why chlorine has a low boiling point whereas sodium chloride has a high boiling point.
Write the electronic configuration for a chlorine atom.
State the meaning of electrolysis.
State the direction in which both the positive and negative ions move when molten sodium chloride is electrolysed. positive ions ……… negative ions ………
State one observation that can be seen at the positive electrode when molten sodium chloride is electrolysed.
Give the formulae of the two negative ions found in aqueous sodium chloride.
When aqueous sodium chloride is electrolysed, hydrogen is produced at the negative electrode. Explain, in terms of electron transfer, why hydrogen rather than sodium is formed at the negative electrode.
