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?
