Saponification is a process by which triglycerides are reacted with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt, called "soap." The triglycerides are most often animal fats or vegetable oils. When sodium hydroxide is used, a hard soap is produced

Dude there is no formula but a reaction.

The reaction is:

CH3COOC2H5 ------------>CH3COONa + H20

This reaction takes place in the presence of sodium hydroxide (NaOH).
