- acid-base titration i abstract the purpose of the laboratory experiment was to determine equivalence points, pka, and pkb points for a strong acid, hcl, titrated with a strong base, naoh using a drop by drop approach in order to determine completely accurate data. Titration is most often used to analyze the amount of acid or base in a sample or solution in acid-base chemistry in a titration experiment, a known volume of an acid solution would be titrated by slowly adding dropwise a standard solution, whose concentration is accurately known, of a strong base. This was one of the limitations in this acid-base titration lab as the indicators that were used did not show a change in color at an exact value of ph but only changed in a specific range of the ph for example, the indicator bromocresol green changes the color of the solution of a ph range between 38 to 54. The reaction between acid and base often yields the products of salt and water the formation of water in this neutralization reaction is caused by the combination of h3o+ and oh- ions in order to determine the concentration of an unknown acid and base, a method called acid-base titration is used.
