Why does the skin of your finger shrink when you wash clothes for a long time?
 

Answers (1)

Answer:

Skin cells lack cell wall and their cell membrane is directly exposed to soap solution or detergent water which acts as hypertonic solution compared to a cellular fluid. When cells are exposed to hypertonic solution, water moves out of the cell as cell membrane is semi permeable and this leads to shrinking of skin cells which makes your fingers look shrinked. The process of water moving out of a cell in a hypertonic solution is called exosmosis.
