Question

Dry apricot placed in salt solution does not swell while they swell when kept in water. Why?

Answer 1

Explanation:

1. Dry apricots kept in water swells up due to osmotic entry of water into it. Water is hypotonic as compared to the cell contents.
2. Dry apricots kept in salt solution do not swell up, since the salt solution is a hypertonic solution, so water cannot enter from the hypertonic solution into the apricot.
3. Dry apricots will swell up only if it is kept in a hypotonic solution like water.
