The osomotic pressure pi depends on the ...

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.

A

"Molarity"

B

"Vapour pressure"

C

"Osmotic pressure"

D

"Viscosity"

The correct Answer is:
To answer the question regarding the glucose solution to be injected into the bloodstream, we need to consider the concept of isotonic solutions and osmotic pressure. ### Step-by-Step Solution: 1. **Understanding Osmotic Pressure**: - Osmotic pressure (π) is defined by the formula π = CRT, where C is the molar concentration of the solute, R is the universal gas constant, and T is the absolute temperature. - This means that the osmotic pressure of a solution is directly proportional to its solute concentration. 2. **Isotonic Solutions**: - Two solutions are said to be isotonic if they have the same osmotic pressure. This implies that they have the same concentration of solute particles in solution. - When two solutions are isotonic, there is no net movement of water across a semipermeable membrane, which is crucial for biological systems. 3. **Application to the Question**: - For a glucose solution to be safely injected into the bloodstream, it must have the same osmotic pressure as the blood plasma. - This ensures that the glucose solution does not cause any osmotic imbalance, which could lead to either excessive swelling of cells (if the solution is hypotonic) or dehydration of cells (if the solution is hypertonic). 4. **Conclusion**: - Therefore, the glucose solution to be injected into the bloodstream should be isotonic with blood. This means that the molar concentration of the glucose solution must be equal to that of the blood plasma. ### Final Answer: The glucose solution to be injected into the bloodstream and the blood itself should have the same osmotic pressure, making them isotonic. ---
