CHMA11H3 Chapter 2: CHMA11 Chapter 2

Mass of KCl in solution = 3.78 g
Mass of water in solution = 12.61 g
Use this information to find the mass of KCl that would dissolve in 100 g of water. This asnwer is your experimental solubilitiy of KCl in units of g KCl/100g water.

Hint:

Use the ratio below.

Mass of KCl)/Mass of solution = solubility/ 100

In order for sodium chloride to dissolve in water, a small amount of energy must be added during solution formation. This is not energetically favorable. Why is NaCl soluble in water?
