Question

For each of the following circumstances indicate where the calulated molarity of NaOH would be lower, higher, or unaffected. Explain your answer

a. The inside of the pipet used to transfer the standard HCL solution was wet with water

b. You added 40 ml of water to the titration flask rather than 25ml

c. The buret wet with water , was not rinsed with NaOH solution before filling the buret with NaOH solution.

d. Five drops of phenolpthalein were added to the solution to be titrated rather than 3 drops.

Explanation / Answer

a. The inside of the pipet used to transfer the standard HCL solution was wet with water = Calculate molarity of NaOH is higher.

b. You added 40 ml of water to the titration flask rather than 25ml = Calculate molarity of NaOH is higher.

c. The buret wet with water , was not rinsed with NaOH solution before filling the buret with NaOH solution = Calculate molarity is lower.

d. Five drops of phenolpthalein were added to the solution to be titrated rather than 3 drops = Calculate molarity is unaffected.
