Question

If you are provided with some vegetables to cook,you generally add salt in to the
vegetables. After adding salt vegetables release water. Why ?

Answer 1

Exosmosis is the process of movement of water molecules from the inner portions of the cell outside, where the solution is hypertonic due to the presence of salt and thus by adding salt to the vegetables it releases water.

The same principle is used in pickling, where the mangoes (or any other fruit) are soaked in a hypertonic solution of salt.

Then the mangoes will ooze out water and the cell becomes flaccid. This process is called as an exosmosis.
