They no longer exist. They exist in solution. They evaporate. They combine with water to form new elements.
I gave my students this multiple choice question: Sugar is made up of many molecules. When sugar is dissolved in water, what happens to these molecules?

Only one answer is correct among these 4 choices:
- They no longer exist.
- They exist in solution.
- They evaporate.
- They combine with water to form new elements.

Could you tell me which one is correct?

They exist in solution.
