Conceptual Challenge Problems

These rigorous, thought-provoking problems integrate conceptual learning with problem solving and are suitable for group work.

CP14.D (Section 14.6) Predict what will happen if you begin to add a 0.010-M solution of Fe³⁺⁽aq) drop by drop to a 5-Ml sample of the stock solution (described in the first paragraph) until the total volume becomes 10 mL. (A 0.010-M solution of Fe³⁺ ions is pale yellow.) Predict what will happen if you do the same experiment but add 0.010-M SCN^-(aq) to the stock solution. Predict what will happen if you mix 0.010-M Fe³⁺(aq) with 0.010-M SCN^-(aq). Would the results of these three experiments be similar or different? Explain.
