Question

Rbc shrink when placed in saline water but swell in distilled water

Answer 1

When RBCs are placed in a hypertonic salt solution, water moves from inside the cell to the outside by osmosis. This causes the cells to shrink. When RBCs are placed in distilled water, a hypotonic solution, water moves from outside of the cell to the inside, causing the cell to swell and rupture

...Distilled water is an example of a hypotonic solution, meaning it has less solute in it than a red blood cell. ... In a hypotonic environment however, water would rush into the red blood cell in an attempt to reach equilibrium, which would cause the red blood cell to expand, and perhaps even burst...
