Solubility and purification of water
- Solubility curves
- Different amounts of substances can dissolve in a
solvent, e.g water at different temperatures
- The effect is shown on a solubility graph/curve
- Desalination of water
- Humans cannot drink sea water, there is
technology for desalination of water, but there
are problems with this on a large scale
across the world
- It uses more energy than the
other process
- It is a very expensive process, many
countries that have the most need for
water are poor and cannot afford
desalination
- The process produces greenhouse
gases, while other treatment plants
produce very little
- The salty water left after fresh water has been
extracted is a pollutant
- Countries with no coastline
would have to pump the water
across large distances
- Distillation
