Q. Gargling with a solution of table salt is known to provide relief for a sore throat because ____ ?
Answer: It dehydrates water from inflammatory tissues by Osmosis
Notes: Gargling with salt water provides relief for a sore throat primarily because it dehydrates water from inflammatory tissues through osmosis. This process reduces swelling and discomfort. Saltwater creates a hypertonic solution, drawing excess fluid out of swollen tissues, which can alleviate pain and irritation. Additionally, salt has mild antibacterial properties, but its primary benefit in this context is osmotic dehydration.
