**Ranking Weak Acids and Bases by pH**

Consider the following data on some weak acids and weak bases:

|   acid name    | formula | \( K_a \)     |
|----------------|---------|---------------|
| hypochlorous acid | HClO    | \( 3.0 \times 10^{-8} \) |
| nitrous acid     | HNO\(_2\)  | \( 4.5 \times 10^{-4} \) |

|   base name   | formula     | \( K_b \)     |
|---------------|-------------|---------------|
| aniline       | C\(_6\)H\(_5\)NH\(_2\) | \( 4.3 \times 10^{-10} \) |
| hydroxylamine | HONH\(_2\)    | \( 1.1 \times 10^{-8} \)  |

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.

| solution            | pH        |
|---------------------|-----------|
| 0.1 M NaNO\(_2\)    | [Dropdown]|
| 0.1 M HONH\(_3\)Cl  | [Dropdown]|
| 0.1 M KClO         | [Dropdown] |
| 0.1 M KCl          | [Dropdown] |
