**Consider the following data on some weak acids and weak bases:** **Acid:** | Name | Formula | \( K_a \) | |----------------------|---------|-----------------------| | Hydrocyanic acid | HCN | \( 4.9 \times 10^{-10} \) | | Hypochlorous acid | HClO | \( 3.0 \times 10^{-8} \) | **Base:** | Name | Formula | \( K_b \) | |---------------|-------------|-----------------------| | Hydroxylamine | HONH\(_2\) | \( 1.1 \times 10^{-8} \) | | Aniline | C\(_6\)H\(_5\)NH\(_2\) | \( 4.3 \times 10^{-10} \) | Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. **Solutions:** | Solution | pH | |-----------------------|------------| | 0.1 M KCl | [choose one] | | 0.1 M C\(_6\)H\(_5\)NH\(_3\)Br | [choose one] | | 0.1 M HONH\(_3\)Cl | [choose one] | | 0.1 M KCN | [choose one] |
