Answer to Question #308639 in General Chemistry for Manuel

Question

What is the molarity of a sodium hydroxide solution if 4.50 mL of the solution is titrated to the end

point, with 5.00 mL of acetic acid with 0.0830M?

Answer 1

NaOH + HAc = NaAc + H₂O;

C₁ * V₁ = C₂ * V₂;

C(NaOH) * V(NaOH) = C(HAc) * V(HAc);

C(NaOH) = C(HAc) * V(HAc) / V(NaOH) = 0.0830 * 5 / 4.5 = 0.0922 M.

Answer: 0.0922 M.
