Water loopy Power Point . Ionic compounds tend to be more soluble than covalent compounds in water. Solubility is measured in g/l at a particular pressure. When a saturated solution is cooled more solute will dissolve in it. Solute: solid Solvent: liquid Soluble: will dissolve

Ionic compounds tend to be more soluble than covalent compounds in water.
When a saturated solution is cooled more solute will dissolve in it.
Solute: solid Solvent: liquid Soluble: will dissolve Insoluble: won’t dissolve Solution: solute dissolved in solvent
The amount of substance that will dissolve in a solvent is affected by the temperature of the solvent.
Gases behave in the opposite way to solids in the way they dissolve in water.
Solubility (g/ 100 g water) Pressure (atm) This graph shows the solubility of oxygen in water at 0oC.
Fizzy drinks are made by dissolving oxygen in water at high pressures.
Soft water contains dissolved substances such as calcium and magnesium salts.
Washing in hard water uses more soap, making it more expensive.
Hard water cools over night in central heating systems. This furs up heating elements making them inefficient.
Water can be softened by using magnesium carbonate (washing soda) or an ion-exchange column.
Filtering using fine sand and adding bromine help to prepare water for drinking.
