Learning Objectives: To understand what is meant by the term ‘concentration of a solution’
Concentration The amount of a substance dissolved in a liquid, (always water as far as we are concerned) is called the concentration. More concentrated solutions have more substance dissolved in them than less concentrated (more dilute solutions). less concentratedmore concentrated (more dilute) (less dilute)
A soluble solute dissolves in a solvent to form a solution. Meanings: SolubleA substance that will dissolve. SoluteThe substance that dissolves (e.g. salt). SolventThe substance in which the substance dissolves (e.g. water). SolutionThe mixture of the solute and the solute (e.g. salty water)
The dots represent particles of solute dissolved in water. Few particles dissolved in the solvent gives a dilute, (not very concentrated) solution. More particles dissolved in the same volume of solvent gives a more concentrated, less dilute solution.
