Swirl the conical flask during the titration to ensure the solutions are mixed. To ensure reliability in a titration: Carry out at least two accurate titrations and calculate an average titre.

For the sample, 6 g tobacco is placed in a 500 mL Schott flask into which 2 g barium hydroxide octahydrate is then placed and stirred. Following this, 30 mL saturated barium hydroxide solution is ...
