Detailed explanation-1: -An oft-cited remedy for a sore throat is to gargle salt water. This can be very beneficial, and it is an example of osmosis.

Detailed explanation-2: -Using saltwater creates a sort of osmosis effect and the salt concentration draws fluids from your mouth that are painful, and it also helps to relieve a painful infection. The saltwater breaks up mucus and irritants and all sorts of fungi from the throat.

Detailed explanation-3: -When you gargle with salt water, the saline solution coats your mouth and throat. This can help loosen mucus, lessen inflammation, and ease throat pain. Gargling with salt water may also eliminate the virus or bacteria that causes a sore throat.

Detailed explanation-4: -Saline water is a hypertonic solution and when we gargle using saline water, osmosis occurs. Gargling with a higher percentage of salt draws the liquid or moisture out of the swollen throat tissues and bacterial pathogens.

Detailed explanation-5: -Saltwater won’t actually cure a sore throat, but it can help reduce pain and discomfort. This is because saltwater has hypertonic properties; in other words, the osmotic pressure in saltwater is higher than the pressure in the fluid of the surrounding cells.
