C3-Hardness of water
Soft water
- Makes a nice lather with soap
- No scum or scale
- Cheaper - however no known health benefits
- No scum or scale
- Makes a nice lather with soap
Hard water
- Scum occurs when adding soap
- Calcium and magnesium ions make the water hard
- Reacts with soap to make scum which is insoluable
- Need more soap to get a lather - more expensive
- When heated, hard water forms scale (CaCO3) on the insides of pipes/kettles.
- This reduces the efficiency and may need to be replaced. This can block pipes.
- Rain falling on rocks such as limestone/chalk can dissolve compounds like MgSO4 (it is soluable)
- Goof for teeth and bones and less risk of hear disease.

Temporary hard water - Softened by heating. Caused by hydrogencarbonate ions
- Permanent hard water - Can only be softened by removing/replacing calcium/magnesium ions
- Caused by dissolved calcium sulfate.
- Permanent hard water - Can only be softened by removing/replacing calcium/magnesium ions
