acidic or basic
« on: April 11, 2015, 03:27:23 AM »
Hi guys! Could you please explain how or why the answer to my question below is acidic?

If equal amounts of HNO2 (Ka = 4.5 x 10 -4) and C6H5NH2 (Kb = 4.2 x 10 -10), the resulting solution will be?

In general it is about comparing strengths of the produced base and acid. Whichever is stronger will dominate the solution (making it acidic or basic).
