Finding out how much acid there is in a solution
Aim
To find out how much acid there is in the solution of sodium carbonate by using a method called titration. A Titration is a method of quantitative analysis which can be used when two solutions react together.
Outline
Using an indicator would show me the end point of the titration, but different indicators are suitable for different combinations of strong weak acids and alkalis. Since this reaction involves a strong acid and a weak alkali, a suitable indicator to use will be methyl orange.
By finding an average titration I will be able to calculate how much acid there is in a solution. From the titration results the amount of sodium carbonate can be calculated. Then, using the equation N= CxV/1000 ( N= amount of substance in mol, C= Concentration of solution in dm³, V= volume of solution in dm³) to determine the number of moles in the second reagent. From the equation the amount of sulphuric acid can be determined. Finally the concentration of sulphuric acid can be calculated by scaling to 1000cm³
