Likewise, if a strong base is added, the weak acid will associate with OH- ions. Buffers are most effective when the concentrations of the acid and base are equal. In this experiment, acetic acid and sodium acetate will be combined to create a buffer solution with a pH approximately equal to its pKa.

In equation 1, the acid is HCl (called hydrochloric acid) and the base is NaOH (called sodium hydroxide). When the acid and base react, they form NaCl (sodium chloride), which is also known as table salt. The titration proceeds until the equivalence point is reached, where the number of moles of acid is equal to the number of moles of base.

Titrations Made Easy. Thus far in our Acids and Bases Unit we have balanced acid/base chemical reactions and studied acid/base conjugate pairs, examined how acid/base indicators work, practiced a variety of calculations using pH, pOH, [H30+] and [OH-], and distinguished between weak and strong aqueous solutions of acids and bases.

The fact that it is an acid allows us to quantify the amount of aspirin in a solution by using an acid-base titration. In this experiment the base used is sodium hydroxide (NaOH). The chemical structure of aspirin is shown below: Preparation. Make sure you wear gloves and safety goggles at all times.

Chemical Analysis by Acid-Base Titration. Introduction: Titration is a common method of determining the amount or concentration of an unknown substance. The method is easy to use if the quantitative relationship between two reacting solutions is known. The method is particularly well-suited to acid-base and oxidation-reduction reactions.

The choice of which weak acid or base to use is based on the pH you want in your reaction and the pKa of the acid/base. Solutions of weak acids/bases are able to buffer best (resist changes in pH) when they are made up within 1 pH unit either side of their pKa.
