Isotonic Solutions and their Characteristics
An isotonic solution refers to a solution that has the same concentration of solutes as another solution. In an isotonic solution, there is no net movement of water across a semipermeable membrane because the osmotic pressure is equal on both sides. Let's discuss each option provided and determine which one is not correct.
a) They will have the same osmotic pressure
Isotonic solutions have the same osmotic pressure. Osmotic pressure is the pressure required to prevent the movement of solvent molecules from a solution of lower solute concentration to a solution of higher solute concentration through a semipermeable membrane.
b) They will have the same vapor pressure
Isotonic solutions do not necessarily have the same vapor pressure. Vapor pressure refers to the pressure exerted by the vapor molecules above a liquid when it reaches equilibrium with its surroundings. The vapor pressure of a solution depends on the concentration of solutes and their nature, so it may vary between isotonic solutions.
c) They have the same weight concentrations
This statement is not correct. Weight concentration refers to the ratio of the weight of solute to the weight of the solution or solvent. In isotonic solutions, the weight concentration may not be the same because different solutes can have different molecular weights and concentrations. Therefore, option C is the correct answer.
d) Osmosis takes place when the two solutions are separated by a semipermeable membrane
Osmosis occurs when two solutions of different concentrations are separated by a semipermeable membrane. Water molecules move from the solution with lower solute concentration to the solution with higher solute concentration, leading to the equalization of solute concentrations on both sides of the membrane. This process is responsible for maintaining osmotic balance in cells and organisms.
In conclusion, among the given options, the statement that isotonic solutions have the same weight concentrations is not correct. Weight concentrations can vary depending on the nature and molecular weight of the solutes present in the solutions.
