Laboratory question:
I have a solution of a known amount of Sulfuric acid as a catalyst. The reaction is a esterfication of the two reactants ethanol and acetic acid with known amounts, and the Product is ethyl acetate and water. When the reaction reach equilibrium, the purpose is to figure out how much acetic acid is left (still reactant). The only permissible method for this is titration with NaOH and find the amount unreacted acetic acid, but there is a problem, we also have the catalyst in the solution. How can we make a titration and figure out the amount of acetic acid ?

Place a circle around the key tetrahedral intermediate. In your
mechanism, note where there are similarities and differences
between the acid catalyzed and non-catalyzed (sic) version by
identifying the steps involving H+.

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1157 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 14.02 mL of the standard solution. What...
