    Isotonic solutions have different osmotic pressure.

    The osmotic pressure of equimolar solutions of BaCl_(2) , NaCl ,and glucose follow the order

    The osomotic pressure pi depends on the molar concentration of the solution (pi=CRT) . If two solutions are of equal solute concentration and, hence, have the same omotic pressure, they are said to be isotonic. If two solutions are of unequal osmotic pressures, the more concentrated solution is said to be hypertonic and the more diluted solution is described as hypotonic. Osmosis is the major mechanism for transporting water upward in the plants. Answer the following questions: The glucose solution to be injected into the bloodstream and the blood itself should have the same.
