This page tests your ability to predict precipitation. The problems are generic in that the metal is represented as M and the anion as X. To begin, press "New Problem" and a question will appear. Determine whether a precipitate will form and click on the appropriate circle. The results on the problem and a running total will appear in the table. If you get a problem "incorrect", a complete solution will appear and you will no longer be aboe to submit an answer to that problem.
