Using the term water potential, explain why the onions ; (i)gained mass when soaked in dilute solutions of sodium chloride (ii)lost mass when soaked in concentrated solutions of sodium chloride

Step-by-step answer

P Answered by PhD

when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis.

Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.
