ACID - BASE TITRATION AIM The aim is to perform an experiment involving the titration of an acid and base to find the end-point of the titration in order to determine the molarity of the sulphuric acid. GENERAL BACKGROUND According to Bronsted and Lowry (1923) an acid is defined as a proton (H+) donor, and a base as a proton (H+) acceptor. For example, sulphuric acid, a strong acid, is a good proton donor while sodium hydroxide, a strong alkali (soluble base) contains the hydroxide ion (OH-) which is a strong proton acceptor. The alkali which produces this OH- ion will neutralize acids by the reaction: H+(aq) + OH-(aq) --> H2O(l) This reaction is common to all neutralization reactions between acids and alkalis in aqueous solution. It should be noted that in aqueous solutions the H+ ions exist in their hydrated forms H+(aq). The most accurate method of measurement...
