A cell with lots of salt inside it is placed in a vessel containing just water. Which process takes place?(a) Dialysis(b) Filtration(c) Shriveling(d) OsmosisI had been asked this question in final exam.The doubt is from Colligative Properties and Determination of Molar Mass in portion Solutions of Chemistry – Class 12

Answer»

Correct answer is (d) Osmosis

To explain I WOULD say: Osmosis is a mass transfer process due to which water MOLECULES MOVE from a REGION of higher water potential to lower water potential down the potential gradient. Dialysis and filtration are processes using the concept of diffusion of impurities. Shriveling is the SHRINKING of a cell. In this case, the cell swells up.
