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 ...

The more concentrated the solution of an acid, the lower its pH will be. If the hydrogen ion concentration in a solution increases by a factor of 10, the pH of the solution decreases by 1 unit.
