The freezing point of diet soda is higher than the freezing point of regular soda, but lower than 0 degrees celcius, the freezing point of pure water. explain why both diet and regular soda freeze at temperatures lower thaan 0 degree celcius

Explanation:

Both Diet Soda and regular soda contain sweeteners.

When a solute is dissolved in solution, the solution undergoes *freezing point depression* it freezing point reduces. The magnitude of freezing point depression is directly proportional to the amount of solute in a solution.

Since soda Both regular or diet soda contains more solute than water , their freezing point is will consequently be lower than water
