Title: Factors Affecting Dissolving and Physical Properties of Solutions Phenomena (Starter Activity): Why do different substances dissolve differently in ____, and how can that change a solution’s properties? Claim: Different substances dissolve at different ____, depending on factors like ____, surface area, and agitation. When substances dissolve, they can also change the solution’s ____ characteristics such as pH, density, ____, and color. Proof: Smaller solute pieces have ____ surface area, so they dissolve faster. Increasing ____ (by stirring) helps the solute mix more quickly with the solvent. A ____ temperature makes particles move faster, helping the solute dissolve more easily. Different solutes can ____ how the solution tastes, feels, looks, or even how it conducts electricity. Result: The rate of dissolving and the kind of solute both affect the solution’s overall behavior and its ____ like pH, density, conductivity, and color.
