Question

Why is it possible to titrate a reaction mixture directly to find the equilibrium concentrations during the following reaction:

 

3 A student carried out an experiment to determine the equilibrium constant for the reaction to form ethyl ethanoate from ethanol and ethanoic acid. CH;COOH + CH,CH,OH = CH,COOCH,CH, + H,0 Different amounts of each substance were added to conical flasks, each containing 2.0 cm of 1.0 mol dm hydrochloric acid. -3 Volume added / cm .3 Conical HCL H,O (1) CH,COOH (1) CH,COOCH,CH, (1) flask CH,CH,OH (1) (aq) 2.0 1.0 2.0 2.0 5.0 0. 5.0 3 2.0 4.0 3.0 4 2.0 0. 3.0 The flasks were then stoppered and left for a week to reach equilibrium. -3 Each mixture was then titrated with 1.0mol dm sodium hydroxide.
