ABSTRACT
Hydrolysis is a chemical decomposition involving breaking of a bond and the addition of elements of water. In this hydrolysis of ester (ethyl acetate) with an alkali (sodium hydroxide), HCl was used as catalyst to accelerate it. 1ml and 2ml of ethyl acetate was injected separately into the500ml reactor vessels which contains 0.05N of NaOH and thoroughly mixed. At regular time
interval, 0, 10, 20, 30, 40, and 90 minutes, 25ml of each of the samples were withdrawn into a250ml conical flask containing 0.05N HCl, and titrated against 0.05N NaOH solution using
phenolphthalein as indicator. From the titre values, the hydrolysis involving the 1ml ethyl acetatewas faster than that of the 2ml ethyl acetate, indicating that the higher the concentration the faster
the rate of reaction. The rate constant after evaluation from the graphs was approximately
