Question
Consider the two statements given below, where one is
labeled as Assertion (A) and the other as Reason (R): Assertion (A): The mixture of salt and ice achieves a temperature below 0°C. Reason (R): Addition of salt raises the melting point of ice. Which one of the following options is correct regarding these two statements?Solution
• When salt (sodium chloride) is mixed with ice (solid water), the mixture can attain a temperature lower than 0°C. Thus, Assertion (A) is true. • However, the addition of salt does not raise the melting point of ice; rather, it lowers the freezing point of water, meaning that ice melts at a lower temperature than usual. Thus, Reason (R) is false. Therefore, the correct answer is (c) A is true but R is false.
