RAW DATA AND OBSERVATIONS Table 1: Volume of Sodium Hydroxide Required for each Titration (4 marks) Table 2: Weighing of Solid Acid Samples (Analytical Balance) (3.5 marks)
Titration of the solid acid samples with standardized NaOH(aq) Concentration of NaOH used: molL−1(0.5 marks) Indicator: (0.5 marks) Endpoint colour change: pale pink (0.5 marks) Table 3 Volume of NaOH Required (3 marks) INSTRUCTOR'S INITIALS and DATE: CALCULATIONS FOR PART 1 1. Write the molecular and the net ionic equations for the neutralization reaction. (2 mark) 2. Use the molecular or net ionic equation for the reaction to calculate the number of moles of sodium hydroxide that were used in the neutralization reaction. (4 marks) 3. Calculate the concentration in molL−1 of sodium hydroxide in the solution. This is the standardized base that will be used in Part 2 and its concentration will be used in later calculations. (2 marks)
