Vocabulary: concentration, dissolve, homogeneous mixture, solubility, solubility curve, solute, solution, solventPrior Knowledge Questions (Do these BEFORE using the Gizmo.)1. What happens when you stir a spoonful of sugar into hot water? 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. If you can’t see the sugar, how can you tell that it is there? 3. Does sugar dissolve more easily in hot water or cold water? Gizmo Warm-upA solution generally consists of two parts, a solute that is dissolved and a solvent that the solute is dissolved into. For example, sugar is a solute that is dissolved into the solvent water. In the Solubility and TemperatureGizmo™, 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? What is the solvent? 2. Click Add 10 g to mix 10 g of potassium nitrate into the water. A. Did all of the potassium nitrate diss
