I. When 50 mL of phenol and 50 mL of aniline are mixed, predict whether the volume of the solution is equal to, greater than or less than 100 mL. Give reason to support your answer.
II. Ritesh suggested adding salt to the box containing ice. He said this would keep the cold drink bottles cold for a longer time. How will Ritesh justify his suggestion?
What happens at the molecular level when phenol and aniline are mixed—do they interact chemically or physically?
Would mixing phenol and water or aniline and water give the same volume effect? Why or why not?
Can the interaction between phenol and aniline cause any temperature change during mixing?
Does the addition of salt to ice affect the melting point of ice? How does this relate to keeping drinks cold?
Could any other substances besides salt lower the temperature of ice further? Name one and explain the principle.
