Title: Volumetric Analysis Aim: To determine the concentration of hydrochloric acid solution Preparation of standard solution: ● Outline a procedure for the preparation of a suitable concentration of sodium carbonate. The acid solution is approximately 0.1 mol/dm3 . The overall volume of the standard solution is 250 mL Name a suitable indicator for the titration: _______________________________________ Outline the steps that would be taken for the titration: Aim: To determine the concentration of the hydrochloric acid solution Apparatus: Material: Method (as outlined in previous page) Results Table showing Burette reading/cm3 Final reading Initial reading Volume used Discussion: Calculate the number of moles of sodium carbonate used in titration Calculate the number of moles of HCl used in titration Determine the concentration of HCl in mol/dm3 Hence, determine the concentration of HCl in g/dm3 List three characteristics of a primary standard Explain why sodium hydroxide was not used as a standard solution? Define equivalence point of a titration: Define the end point of a titration: Explain your choice of indicator for this experiment: Conclusion: Further work: Sketch the changes in pH during titration of 25 cm3 sodium carbonate solution with hydrochloric acid.
