The results in the table below were obtained when 25.0cm of 0.1M potassium hydroxide solution was neutralized with sulphuric acid from a burette.
c) Calculate the concentration of sulphuric acid Step I Write a balanced chemical equation for the neutralization between sulphuric acid and potassium hydroxide solution. H2SO4(aq) + 2KOH(aq) K2SO4(aq) +2H2O(l)
Step II
Calculate the number of moles of potassium hydroxide used. Number of moles of sulphuric acid = molarity x volume of acid in litres
