0.9% of NaCl solution is considered isotonic for RBCs. If RBCs are placed in 2% NaCl solution what will happen to the cells? what is such a solution called?
a red blood cell has a concentration of about 0.9% NaCl.
if you put it in a 0.9% NaCl solution, it would be considered an isotonic solution and nothing would happen.
a 0.1% NaCl solution would be hypotonic (less concentrated) and water would flow into the cell, causing it to swell and possibly burst.
a 2% NaCl solution would be hypertonic (more concentrated) and water would flow out of the cell, causing it to shrivel (or crenate).
remember hypo is less, hyper is more, and iso is same. tonic just means particles, and water goes where the particles are more
