Question

___________ is added to a sample of reaction mixture containing acid and ester before titration to stop the reaction.​

Answer 1

Explanation:

way of detecting the smell of the ester is to pour the mixture into some water in a small beaker. Apart from the very small ones, esters are fairly insoluble in water and tend to form a thin layer on the surface. Excess acid and alcohol both dissolve and are tucked safely away under the ester layer.
