Solubility and Temperature Gizmo (50 marks) Muhammad Fauzaan Log into www.explorelearning.com and search for solubility gizmo. Complete the following questions as you conduct the gizmo. Prior Know... ledge Questions (Do these BEFORE using the Gizmo.) 1. What happens when you stir a spoonful of sugar into hot water? < The sugar will dissolve in the 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? < Because the water tastes and looks a little different. If you wanted to see the solute again the you would have to boil the water. > 3. Does sugar dissolve more easily in hot water or cold water? < Hot 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 > This study source was downloaded by 100000830034489 from CourseHero.com on 08-28-2021 02:45:05 GMT -05:00 https://www.coursehero.com/file/62445223/SCN2796-MD-Unit-C-Assignment-C5-Muhammad-Fauzaanpdf/ This study resource was shared via CourseHero.comB. How can you tell? < I can tell this because all the potassium nitrate I added has dissapeared > Activity A: Solubility Get the Gizmo ready: • Click Reset. • Check that the Temp. is 20 °C and that Potassium nitrate is selected. Question: How do we find how much solute can be dissolved in a solvent? 1. Observe: Click OK. Click Add 20 g, and observe the potassium nitrate being mixed into the solution. On the right, select the BAR CHART tab and turn on Show numerical value. The bars show how much solute has been added and how much has piled up on the bottom. Did all of the solute dissolve? < Yes [Show More]
