Potassium hydroxide reacts completely with sulfuric acid according to the equation:
H2SO4(aq) + 2KOH(aq) K2SO4(aq) + 2H2O(l)
0.95 g of potassium hydroxide were dissolved in water and made up to 250 cm3 of
solution. 25 cm3 samples of this solution were titrated against sulfuric acid (H2SO4)solution. The mean volume (titre) of sulfuric acid required for complete reaction was15.00 cm3.
