The salt creates a hypotonic environment, causing bacteria to undergo plasmolysis and die

|
The salt creates a hypertonic environment, causing bacteria to swell with water and burst
|
|
|
The salt creates an isotonic environment, where bacteria can no longer control the flow of water into or out of the cell

Detailed explanation-1: -The salt solution (saline water) is hypertonic and when we gargle with it, comes in contact of infection causing bacteria in the throat. The water present in the bacterial cell comes out causing plasmolysis and they get killed giving us relief from infection.
Detailed explanation-2: -When you gargle with saltwater, you are submerging the cells and drawing liquids to the surface, along with any virus and bacteria in the throat. When you spit the saltwater out, you’ll rid the body of those germs, as well.
Detailed explanation-3: -How does gargling with salt water reduce the pain of a sore throat cause by swollen throat tissues? Answers: Salt water is hypertonic to the fluid in throat tissue cells resulting in a net flow of water out of the cells and a reduction in swelling.
Detailed explanation-4: -Salt water can be gargled to relieve scratchy and sore throats. The salt water helps wash away the mucus that lines the throat and helps reduce inflammation. The method for gargling salt water takes only a minute and a few simple supplies. Repeat several times throughout the day or as needed.
Detailed explanation-5: -In a hypertonic solution, the net movement of water will be out of the body and into the solution. A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.
