Student Exploration Solubility and Temperature Exam 100% Solved

Student Exploration Solubility and Temperature Exam 100% Solved Name: Date: Student Exploration: Solubility and Temperature Vocabulary: concentration, dissolve, homogeneous mixture, solubility, solubility curve, solute, solution, solvent Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What happens when you stir a spoonful of sugar into hot water? The sugar dissolves in the water to form a solution. 2. Does sugar dissolve more easily in hot water or cold water? The sugar dissolves more easily in hot water than in cold water. Gizmo Warm-up A 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 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. Did all of the potassium nitrate dissolve? Yes B. How can you tell? There is a resulting solution with no residue.
