In acidic hydrolysis of ester it is heated with dilute acid (such as dil. HCl, H2SO4 ). On reaction to water ethanoic acid and ethanol are formed and the mixture is in equilibrium.

But in alkaline hydrolysis of ester it is heated with a dilute alkali (such as NaOH). It is one way reaction. The products can easily be separated. As a result sodium salt is formed.

Now the theme:

Acid hydrolysis of an ester produces a carboxylic acid which is a weak acid. This means that it does not ionize fully when dissolved in water. That means the reverse reaction that produces the ester is favored. On the other hand, alkaline hydrolysis produces a carboxylate salt which ionizes fully and signals that the reaction has gone to completion.
