Deducing the quantity of acid in a solution INTRODUCTION: To find the accurate concentration of a solution of sulphuric acid of which concentration is known to be between 0.05 and 0.15moldm-3, using solid anhydrous sodium carbonate and a range of indicators. I have to decide which indicator is most appropriate to use, then plan and carry out an experiment to determine the accurate concentration of the sulphuric acid. BASIC PLAN: * I will make a standard solution of sodium carbonate from the anhydrous sodium carbonate and calculate its concentration. * After making the sodium carbonate solution of known concentration, I will use it to determine the concentration of the sulphuric acid. This will be possible through an acid/ alkali titration. Sodium hydroxide (the alkali), will neutralise the acid in the reaction to produce a salt (Sodium Sulphate - Na2SO4) water and carbon dioxide. Add the acid until solution is neutral (the...
