a. Given the Ka values, estimate the p Ka value of each of the following acids without using a calculator (that is, is it between 3 and 4, between 9 and 10, and so on?): 1. nitrous acid (HNO 2 ), Ka = 4.0 * 10-4 3. bicarbonate 1HCO3 - 2 , Ka = 6.3 * 10-11 2. nitric acid (HNO 3 ), Ka = 22 4. hydrogen cyanide (HCN), Ka = 7.9 * 10-10 5. formic acid (HCOOH), Ka = 2.0 * 10-4 b. Determine the exact p Ka values, using a calculator. c. Which is the strongest acid?
