Titrate the contents of the conical flask by adding to it 0.100 mole dm3 hydrochloric acid from the burette. Add the solution slowly. Swire the flask gently to mix the contents at the end indicator turns as define red colour. This is the end point of the titration. Record the final burette reading in your table of result. Repeat the titration

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed
