Why does the skin of your finger shrink when you wash clothes for a long time?
Advertisements
उत्तर
Soap solution is a hypertonic solution i.e., it is more concentrated than the cells of our skin. As we know when a cell is immersed in a hypertonic solution, water leaves the cell by the process of exosmosis resulting in shrinkage of the cell. In the same way, while washing clothes for a long time, exosmosis occurs in the skin cells resulting in the shrinkage of skin cells of our fingers.
