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
Initial NaOH Buret Reading
0.0 mL
12.2 mL
23.2 mL
Final NaOH Buret Reading
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!
Answer

M

  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.
