Question

a. Plot your titration data (volume of NaOH used on the x-axis and the corresponding pH value on the y-axis)

1. Phosphoric Acid + Sodium Hydroxide

2. Al3+ + Sodium Hydroxide

1. Graphing your results: Plot your titration data (volume of NaOH used on the x-axis and the corresponding pH value on the y-axis). Make the graph large enough so that it occupies most of the page; but also pick a size which allows you to divide the x- and y-axes into easy-to-read increments. One graph for each of the following titrations: + Hydrochloric Acid + Sodium Hydroxide *. Atctic Acid + Sodium Hydroxide iii. Phosphoric Acid + Sodium Hydroxide iv. Al3+ + Sodium Hydroxide b. Be sure to: i. Title your graph, e.g., “pH Titration of HCl(aq) with 0.10 M NaOH”. ii. Label the axes, including units. iii. Label the endpoint of each titration and neatly write the pH value and volume of NaOH required to reach the endpoint. iv. Label the midpoint of each titration and neatly write the pH value of and volume of NaOH required to reach the midpoint. v. On your graph indicate what pH indicator was used and the color of the solution that you recorded. vi. For each reaction that you performed, turn in a neat table of the data that you collected
