www.ccri.eduThe pKa and molar mass of a weak acid can be obtained from its titration curve, a plot of pH versus volume of added base. The equivalence point is half way up the vertical part the titration curve. At the equivalence point, all the weak acid, HA, has reacted completely with an equivalent amount of base.

kimia.um.edu.myACID BASE TITRATION Objective : To determine pH curve for titration of strong acid-strong base and weak acid-strong base. 1 Theory The process of adding acid to a base (or vice versa) to produce a salt and water is called neutralization. In the neutralization of hydrochloric acid with sodium hydroxide, the reaction that occurs is:

academic.brooklyn.cuny.eduMohr titration. The titration was carried out at a pH between 7 and 10 because chromate ion is the conjugate base of the weak chromic acid (2, 3). Therefore, when the pH is lower than 7, chromate ion is protonated and the chromic acid form predominates in the solution. Consequently, in more acidic solutions the chromate ion concentration is too
