Answer 1

The addition of salt to a glass of warm water used as a gargle creates an osmosis effect where the concentration of salt draws fluids from your mouth and throat tissues to relieve a painful infection.

Saline water is hypertonic, it causes plasmolysis of bacterial cells and also draws fluids from your mouth and throat tissues to relieve a painful infection.
