Given below are two statements : Statement (I) : NaCl is added to the ice at 0°C, present in the ice cream box to prevent the melting of ice cream. Statement (II) : On addition of NaCl to ice at 0°C, there is a depression in freezing point. In the light of the above statements, choose the correct answer from the options given below :

1. Statement I is false but Statement II is true
2. Both Statement I and Statement II are true
3. Both Statement I and Statement II are false
4. Statement I is true but Statement II is false

Correct answer: Both Statement I and Statement II are true

Solution

Both statements are accurate because adding NaCl to ice lowers the freezing point, which helps maintain the ice's temperature and prevents ice cream from melting. This phenomenon is known as freezing point depression.
