Statement I: Addition of ethylene glycol (non-volatile) to water lowers the freezing point of water. Statement II: Addition of any substance to water lowers the freezing point of water. |
If both statements are CORRECT, and Statement II is the CORRECT explanation of Statement I. If both statements are CORRECT, and Statement II is NOT the CORRECT explanation of Statement I. If Statement I is CORRECT, but Statement II is INCORRECT If Statement I is INCORRECT, but Statement II is CORRECT |
If Statement I is INCORRECT, but Statement II is CORRECT |
The answer is 4. Statement I is INCORRECT, but Statement II is CORRECT. Statement I: Addition of ethylene glycol (non-volatile) to water lowers the freezing point of water. This statement is incorrect. The freezing point of a solution is determined by the number of particles in the solution, not the type of particles. So, the addition of any non-volatile solute will lower the freezing point of water. Statement II: Addition of any substance to water lowers the freezing point of water. This statement is correct. The freezing point of a solution is determined by the number of particles in the solution, not the type of particles. So, the addition of any solute will lower the freezing point of water. Therefore, Statement I is incorrect, but Statement II is correct. |
