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?
Answer (a) is being explained in the image attached.
Answer (b) : If the human red blood cells were placed in pure water, the cells would undergo the process of osmosis and swell up. These cells would ultimately burst out due to pressure building up within them. An isotonic solution is the one having similar osmotic pressure between the two solutions that are usually separated by a semipermeable membrane. So the movement of water is free in such solutions.

When blood cells are placed in a 0.50% (m/v) solution of NaCl, this is considered: crenation isotonic hypotonic hypertonic Question 19 (4 points) Saved When blood cells are placed in a 0.9% (m/v) solution of NaCl, this is considered: isotonic hemolysis hypotonic crenation

If a patient was administered an intravenous dose of this solution, what would happen to their red blood cells? What would be a likely initial symptom of high levels of Na* and CI? C. Read the label on the 0.9 % Sodium Chloride IV solution bag. 1. What is the osmolarity of this solution? Is this solution isotonic, hypertonic or hypotonic? Explain. 2. Is the stated...

Hemolysis of red blood cells occurs when the cells are placed in ain) isotonic solution hypertonic solution hypotonic solution physiological saline solution
1) Suppose you made an intravenous solution, intended to be isoosmotic to red blood cells (i.e., 300 mOsm). You add 5 grams of NaCl to 800 ml of distilled water. Will this solution be isoosmotic to cells? if not, what will happen to the cells? (Will they take in water or lose water?) How would you make 500ml of a 5% NaCl solution? You dissolve 20 grams of glucose into water to give a solution whose final volume is exactly...
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 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.
