Covalent and Ionic Compounds in Water

The video explains the process of dissolving sugar in water, highlighting the difference between ionic and covalent compounds. Sugar, a covalent compound, dissolves by separating into molecules, not individual atoms. In contrast, ionic compounds like salt dissociate into individual ions when dissolved. The video clarifies that covalent bonds remain intact during dissolution, while ionic bonds can break apart.

What is a common misconception about what happens to atoms when sugar dissolves in water?

• Atoms remain unchanged.

• Atoms form new compounds.

• Atoms break apart into individual elements.

• Atoms change their charge.
