• Is a measurement that shows the quantity of solute dissolved in a unit volume of solution, normally in 1 \(\text{dm}^{-3}\) solution.
• The higher the quantity of solute, the higher the concentration of the solution.
• The quantity of solute dissolved can be measured in gram or mole, hence the concentration of a solution can be measured in unit \(\text{ g dm}^{-3}\) dan \(\text{mol dm}^{-3}\).

• Is the mass of solute found in 1 \(\text{dm}^{-3}\) larutan.
•  The formula for concentration in \(\textbf{g dm}^{-3}\) is as belowe:

\(\text{Concentration } \text{(g dm}^{-3}) = \dfrac{\text{Mass of solute dissolved (g)}}{\text{Volume of solution (dm}^3)}\)

• Is the number of moles of solute found in 1 \(\text{dm}^{-3}\) solution.
• This concentration is called molarity.
•  The formula for concentration in \(\textbf{mol dm}^{-3}\) is as bellow

\(\text{Concentration } \text{(mol dm}^{-3}) = \dfrac{\text{Number of moles of solute (mol)}}{\text{Volume of solution (dm}^3)}\)

• The pH of value of acid or alkali depends on two factors as below:

• Even at the same concentration, the pH value still depends on the degree of dissociation:
  • Higher the degree of dissociation of an acid, the lower the pH value.
  • Higher the degree of dissociation of an alkali, the higher the pH value.
• Both acid and alkali depend on their pH value for molarity:
  • High molarity of acid, lower the pH value. 
  • Higher molarity of alkali, higher the pH value.
