Question:
1. It is important to keep the test tube closed to avoid evaporation of water while heating the salt solution.
a) Briefly explain how a loss of water by evaporation would affect the initial calculations of the solubility of your salt.
b) How would this affect your calculated value of ksp?
c) Assuming that the loss of water but evaporation affected all subsequent calculated concentrations in the same manner, how would this ultimately affect the values of delta h and delta s obtained by graphical analysis?
2. Explain the chemical significance of entropy change for dissolution of a salt
