Answer the following question in the essay box below. Effect of Solvent: Record the results. H2O = alcohol = glycerin = In which liquid is the salt most soluble? Using the concept of `'Like dissolves like," explain why you got the results you did. Explain how the choice of solvent affects the dissolving process. Effect of Pulverizing: Record of dissolving times. crystal = pulverized = Why are the dissolving rates different? Effect of Temperature: Record of dissolving times. cold = hot Using the concepts of kinetic energy, describe why you found the results you did. Effect of Stirring: Record the times necessary to dissolve each sample. Record of dissolving time. stirred = unstirred = Perform the experiment again using hot tap water this time. Are there any differences in the results between the cold water experiment and the hot water experiment? Explain. Conclusions: Review the four factors of dissolving you have just investigated. Given the correct solvent for a solute, what could you do to hasten the solution process? 1. 2. 3.
