The results of a titration can be used to calculate the concentration of a solution, or the volume of solution needed. Concentration in mol/dm 3 = \(\frac{moles~of~solute}{volume~in~dm^3}\) ...

Volume of sodium hydroxide solution = 25.0 ÷ 1000 = 0.025 dm 3 Number of moles of sodium hydroxide = concentration × volume Number of moles of sodium hydroxide = 0.3 mol/dm 3 × 0.025 dm 3 ...
