Explain the physical states (under standards conditions) and electrical conductivity (in the molten state) of the chlorides and oxides of the elements in period 3 in terms of their bonding and structure
Summary of Chlorides
Summary of Oxides
13.1.2 – Describe the reactions of chlorine and the chlorides referred to in 13.1.1 with water
NaCl dissolves in water to form a neutral solution. The ions dissociate and assimilate into the solution. There is ion dipole bonding to attract water.
MgCl forms a slightly acidic solution.
The magnesium may also form dative bonds with the water, making the solution slightly acidic.
AlCl3 forms a highly acidic solution. The reaction with water causes spitting and acid fumes
This is a very acidic solution, with dative bonds between the aluminium and the water molecules.
The aluminium ion acts as a Bronsted-Lowry acid
This forms a highly acidic solution
The HCl dissolves to form a highly acidic solution
Forms a highly acidic solution
Reacts to form chlorine water
