Conceptual Challenge Problems
These rigorous, thought-provoking problems integrate conceptual learning with problem solving and are suitable for group work.
CP17.A (Section 17.2) Suppose you were asked on a laboratory test to outline a procedure to prepare a buffered solution of pH 8.0 using hydrocyanic acid, HCN. You realize that a pH of 8.0 is basic, and you find that the Ka of hydrocyanic acid is 4.0 × 10-10. What is your response?
We need at least 10 more requests to produce the solution.
0 / 10 have requested this problem solution
The more requests, the faster the answer.
