A chemist is performing a titration in order to determine the amount of sodium hydroxide, NaOH(aq), in 115 mL of an aqueous solution.

(a) If 29 mL of a 0.14 M HCl solution was used as a titrant to reach the equivalence point, what was the concentration of sodium hydroxide in the initial solution?
M

(b) What was the initial pH of the sodium hydroxide solution?

A sodium hydroxide solution was prepared according to the procedure outlined in this week's experiment. This sodium hydroxide solution was standardized by titration against exactly 10 mL of a 0.2780 M hydrochloric acid solution. In three titrations, the volumes of the sodium hydroxide solution required to reach the equivalence point were 8.83 mL, 8.98 mL, and 8.74 mL.

What is the molarity of your sodium hydroxide solution?

Molarity of NaOH = M

This sodium hydroxide solution was then used to determine the amount of acetic acid in vinegar. Three titrations of the sodium hydroxide solution against exactly 5.0 mL of vinegar using phenolphthalein indicator required 21.15 mL, 20.97 mL, and 21.23 mL of the sodium hydroxide solution.

What is the molarity of the acetic acid in vinegar?

Molarity of acetic acid in vinegar = M
