1. The problem statement, all variables and given/known data Hello all! Say I have an ion XY. I dissolve it in a solution. What is the difference between its dissociation or solubility, or are they the same? Seems my ap chem review book is using these two terms interchangeably and I am just plain confused. Thanks 2. Relevant equations None. 3. The attempt at a solution Just pondered this all day long.
