Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -This phenomenon is called plasmolysis. The other benefits are; when the salt water enters the throat, the solution helps to neutralize acids in the throat, restoring the natural pH balance that had been disrupted by the sore throat.
Detailed explanation-4: -To see an easy demonstration of osmosis, soak gummy candies in water. The gel of the candies acts as a semipermeable membrane. Examples of Diffusion: Examples of diffusion include perfume filling a whole room and the movement of small molecules across a cell membrane.
