A. Introduction The purpose of this experiment was to determine the rate of a nucleophilic substitution reaction, during which t -butyl chloride was hydrolyzed. The reaction can be classified as a nucleophilic substitution reaction because t -butyl chloride is transformed from an alkyl halide to an alcohol as a result of the displacement of its chlorine atom by water. To study the kinetics of a reaction, the time of the rate of disappearance of the reactants or the rate of appearance of the products must be observed. Conventionally, an acid-base titration would be used to determine the rate of the reaction by observing the amount of acid produced. Instead, in this experiment, an acid-base indicator was used for the convenience of time. By adding one-tenth an equivalent of sodium hydroxide solution to the t -butyl chloride, one-tenth of the reaction time of the hydrolysis could be measure by observing when the acid-base indicator (bromophenol blue) created a color change. In the experiment, reaction was done at room temperature, in a hot water bath,
