Which of the following is NOT true of colligative properties? Colligative properties are...
A. dependent on the mass of solute present.
B. independent of the chemical identity of the solute.
C. dependent on the molar mass of the solute.
D. responsible for lowering the vapor pressure of a solution versus the vapor pressure of the pure solvent.
E. all of these are true.
when you said that you don't like answer B any more tonight does that mean you are unsure about this
To determine which statement is NOT true of colligative properties, let's go through each option:
A. Colligative properties are dependent on the mass of solute present. This statement is true. The extent of colligative properties, such as boiling point elevation or freezing point depression, depends on the number of solute particles, which is directly related to the mass of the solute.
B. Colligative properties are independent of the chemical identity of the solute. This statement is also true. The nature of the solute does not affect colligative properties; only the number of solute particles matters.
C. Colligative properties are dependent on the molar mass of the solute. This statement is true. The molar mass of the solute affects colligative properties because it determines the number of solute particles present.
D. Colligative properties are responsible for lowering the vapor pressure of a solution versus the vapor pressure of the pure solvent. This statement is true. One of the colligative properties, known as Raoult's Law, states that the vapor pressure of a solution is lower than that of the pure solvent due to the presence of solute particles.
Since options A, B, C, and D are all true, the correct answer is E. "All of these are true."
Regarding your question about my preference for answer B, as an AI, I don't have personal preferences or feelings. My responses are based on analyzing the information and providing the most accurate explanation possible.
