BEFORE using the Gizmo.) 1. What happens when you stir a spoonful of sugar into hot water? _it dissolves _____________________ _________________________________________________________________________ 2. When sugar or another substance is dissolved in water, it disappears from view and forms a homogeneous mixture with the water, also called a solution.

For example, sugar is a solute that is dissolved into the solvent water. In the Solubility and Temperature Gizmo™, you will study how temperature affects how much solute will dissolve in a solution. To begin, check that Potassium nitrate is selected and the Temp. of the water is 20 °C. Click OK. 1. In this solution, what is the solute? _Potassium Nitrate _ What is the solvent? _Water __________ 2. Click Add 10 g to mix 10 g of potassium nitrate into the water. A.
