Question

blood cells are isotonic with 0.9% nacl solution. what happens if we place blood cells in a solution containing 1.2 %nacl solution and 0.4%nacl solution​

Answer 1

The first case the sodium chloride solution is hypertonic to the blood cell so water comes out of the cell therefore cell will shrink

in the second case sodium chloride solution is hypotonic to the blood cell so water will come in and therefore cell will swell up
