MaterialsOr Youtube video:Question: How does adding more solute (and thus more particles) affect the freezing point of the solution?Hypothesis: (choose one)a)If more particles are added, then the freezing point will be lower because the solute particles will interferewith the solvent’s ability to become a solid, and more energy will need to be removed to freeze the solvent.b)If more particles are added, then the freezing point will be higher because the solute particles will interferewith the solvent’s ability to become a solid, and less energy will need to be removed to freeze the solvent.c)If more particles are added, then the freezing point will be the same because the solute particles will notinterfere with the solvent’s ability to become a solid.ProcedurePart One: Freezing Point1)In the simulation, click on water as the solvent and sodium chloride as the solute.2)Start with 100 g solvent and 0 g solute.3)Click cold, and Start.4)Wait for the freezing point to be reached (the temperature will stay approximately the same).5)Record the data. Click “Micro Level Reaction” to see what is happening at the particle level.6)Repeat with 2g, 4g, 6 g, 8g, and 10g of sodium chloride solute, keeping the solvent at 100 g of water.DATASolute (sodium chloride) amount ingramsSolvent (water) amount in gramsFreezing Point (°C)01000.002100-1.224100-2.306100-3.598100-4.7010100-5.79AnalysisCLAIM : If more particles are added, the freezing point ____lower______EVIDENCE: (choose two data points to support your claim) _higher solute lower freezing point, 10 in solute= thelowest freezing point in the graph_REASONING:As more particles are added, the freezing point _____lower____because(use words like solute, solvent, interferes, freezing )
___the molecules slow down due to the decreases in temperature, and the intermolecular forces start to takeover.___.MaterialsOr Youtube video:Question: How does adding more solute (and thus more particles) affect the boiling point of the solution?
