    Question 6 (1 point) In your pre-lab, you were asked to determine the concentration for a 25.00 mL sample of acetic acid, CH3COOH (K= 1.8 x 10-5) of unknown concentration. Suppose you now repeat that same titration, using another 25.00 mL sample of that same unknown acetic acid and the same concentration of NaOH as a titrant. However, before you start titrating, you add an additional 100 mL of water to the flask containing our sample of acid. Everything else...

    Focus on Step A5 of the procedure, where one partner prepared their sample for visual titration by adding approximately 100mL of water to the to sample in the plastic cup or beaker before beginning the titration. Note that this step was also repeated in the potentiometric (pH-meter) titration in Part 2 (Step A7). In both cases, the addition of more water was an experimental necessity, to allow the solution to be stirred easily and to ensure that the pH probe...
