The concept of Osmosis is frequently used in medical field. On the other hand, reverse osmosis has also found application in desalination process. Both these processes play a very useful role in the growth and development of humankind.
(a)[1.0]
Explain where in medical field the concept of osmosis is used.
(b)[1.0]
The place close to the sea can use reverse osmosis (RO) for desalination. Explain how that can be done.
(c)[1.0]
A saturated salt solution makes a boiled peeled egg shrink. Why?
Answer
Answer (a)
Official answer keyIn dialysis of kidneys the concept of osmosis is used.
Answer (b)
Official answer keyThe sea water contains different concentrations of many salts when they are separated from pure water through semipermeable membrane, the reverse osmosis (RO) takes place and water moves out from the sea water to pure water side.
Answer (c)
Official answer keyAs the salt concentration is less in egg than the saltwater solution, the water from egg moves towards saltwater solution and makes egg shrink.
