Chemistry

A titration setup was used to determine the unknown molar concentration of a solution of NaOH. A .025 M HCl solution was used as the titration standard. The following data were collected.

Trial 1
Trial 2
Trial 3
0.0 mL
12.2 mL
23.2 mL
12.2 mL
23.2 mL
34.0 mL
Volume of NaOH

What molarity is the NaOH used to neutralize 10.0 mL of the standard HCl solution for the average HCl volume? Sig figs!

M

What is the pH of the HCl solution?

What is the pH for the NaOH solution?

1. mLacid x Macid = mLbase x Mbase. Substitute and solve for the unknown.
pH = -log(H^+) but do you want pH of the initial HCl or the pH after neutralization.
