I am taking Biochemistry. However, the prof talked about Inoic Strength in class.

This is the example,

u = 1/2 (Molarity) (ionic charge )^2

Example... .10M CaCl2

u = 1/2 (.10)(+2)^2 + (.20)(-1) ^2

u = 1/2 ( .40 + .20 ) = .30


I opened my Chemistry Textbook..i looked it up Ionic section but I dididn't see it..maybe it has a different name...

My question is....where can I find more info and practice problems about Ionic Strength in Chemistry Textbook. I don't see any equatios like that at all.

I'm sure you will find Ionic Strength discussed in any standard Electrochemistry text (and possibly in a Physical Chemistry text). This is an useful concept for understanding screening of charge in an electrolyte.
