Concentration and Strength

Concentration and Strength:


The term concentration tells us how much a substance is dissolved in 1 dm3 of the solution. This is changeable, of course. By adding more of the substance, we increase its concentration. By adding more of the solvent, we decrease the concentration.


The term strength refers to how easily an acid or an alkali dissociates when dissolved in water. This is a property that is not changeable.
