When RBC placed in a hypertonic solution (High osmolarity),the water molecules moves from the RBC to the hypertonic solution through the semi permeable membrane. it is called EXOSMOSIS and the RBC get SHRUNKEN.
When RBC is place in distilled water(Hypotonic solution), the water molecules moves in to the RBC,it is called ENDOSMOSIS. and the RBC get SWOLLEN up and rupture.
When RBC is placed in 0.9% NaCl solution (isotonic solution that is same osmolarity with the RBC),no movement of water molecules occur and RBC will be in normal shape.

Red blood cells often can be charged. Two red blood cells are separated by 1.36 m and have an attractive electrostatic force of 0.980 N between them. If one of the red blood cells has a charge of +8.32 10-6 C, what is the sign and magnitude of the second charge, Q?

If red blood cells are taken from the body and placed in a hypertonic solution, what happens to the cells? The cells remain unchanged due to equal solute concentrations inside and outside the cells. The cells remain unchanged due to equal water concentrations inside and outside the cells. They become white blood cells. The cells swell and burst because water moves into them. The cells shrivel up because water leaves them.

A 1.1%(m/v) solution of potassium chloride is isotonic with red blood cells. A). is a 0.11M solution of potassium chloride hypotonic, isotonic, or hypertonic with red blood cells? convert the 0.11M potassium chloride solution concentration into % (m/v) to support your answer? please show every step. B). what would happen to the red blood cell immersed in a 0.11M potassium chloride solution- nothing, crenation, hemolysis?

If human red blood cells are placed in an isotonic solution (0.9% NaCl; MW = 58.4; 37°C), they neither gain nor lose water. (a) Calculate the osmotic potential (atm) inside those red blood cells; (b) What would happen to the cells if they were placed in pure water, rather than the isotonic solution? Why?
