Calculate the pH of a solution prepared by mixing 125.0 mL of 0.178 M acetic acid (HC2H3O2) with 150.0 mL of 0.100 M sodium hydroxide, NaOH
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 27.03 mL sample of an unknown phosphoric acid solution is titrated with a 0.112 M sodium hydroxide solution. The equivalence point is reached when 25.57 mL of sodium hydroxide solution is added. What is the concentration of the unknown phosphoric acid solution? Enter a numerical answer only, in terms of M to 4 decimal places.
