Show transcript
Concentration of a solution is the mass of solute dissolved in 1 dm³ of distilled water, in g/dm³.
The more solute that is dissolved, the more concentrated the solution.
Solutions can be diluted (i.e. made less concentrated) by increasing the volume of distilled water.
Diluting solutions with distilled water ensures no other substances are present in the solution.
Volume can be measured in various units; 1 dm³ is equivalent to 1000 cm³.
