Solubility

A measure of the maximum amount of a solute that can be dissolved in a solvent

Solubility is a measure of the maximum amount of a solute that can be dissolved in 0.1 kg of a solvent at a given temperature.

  • solubility is dependent on temperature. In general, but not without expectations, solubility increases with temperature
  • smaller particles dissolves faster than larger particles
  • a solid dissolves faster if the mixture is stirred or shaken

Examples

  • tea with sugar - a solution of sugar and hot water (tea)
  • seawater - a solution of salt and water

If 56 gram salt is dissolved in 0.8 kg water, then  (56/0.8)*0.1 = 7 gram  is dissolved in 0.1 kg water.

0.1 kg water = 100 g water. The percentage solubility can be calculated as

(7 g/100g)* 100%  = 7 %
