Solubility Experiment
Purpose: to explore the relationship with solubility and temperature
Analysis of Observations:
Analyze and Evaluate:
1. Complete your observations by calculating the mass of Epsom salts and table salt in each
case.
2. Calculate the solubility of Epsom salts and table salt in hot and cold water and complete
your table. Show your calculations below.

3. Compare the solubility that you calculated for Epsom salts in cold water and in hot water.
What do you conclude about how the solubility of Epsom salts changes with
temperature?

6. Apply the particle theory to your observations in this activity. How does the particle
theory help explain why the salt dissolves better in warmer water? Why is it difficult to
use the particle theory to explain solubility?
