pH Revisited

Ionic strength represents the measurement of all the ions in the aqueous solution. 

Ionic Strength

Concept #1: Ionic strength can help to increase the overall solubility of an ionic solid. 

Example #1: Calculate the ionic strength of the following ionic compound.

0.010 M CuSO3

Ionic Strength Calculations

Example #2: Calculate the ionic strength for the following ionic compound.

0.030 M Al2(CO3)3

Example #3: What is the ionic strength of a solution that is 0.1 M Na3PO4 and 0.05 M Na2HPO4?

Practice: Calculate the ionic strength for the following ionic compound.

0.04 M SnO2
