Predicting solubility using HSAB and Bronsted acid/base strength
This activity is a guided approach to answering the following: "Give an example of a silver (Ag+) salt that is expected to be soluble in water." It requires students to consider both HSAB and Bronsted acid/base concepts when evaluating solubility.
I use the activity at the end of the unit on reactivity of ions in aqueous solutions, after we have gone over all of the relevant concepts, and the question (without scaffolding) is similar to what I might ask on an exam.
