Solubility and Solutions Concepts

Jimmy, dressed as a magician, demonstrates how substances dissolve in water, explaining the concepts of solute, solvent, and solution. He shows that not all substances dissolve, using sand as an example. The video explores factors affecting dissolving, such as mixing, heating, and time, and identifies various soluble and insoluble substances.

• It dissolves, forming a solution.

• It disappears completely.

• It turns into sugar.

• It remains unchanged.

In a sugar solution, what is the role of water?
