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

| Acid                  | Formula | \(K_a\)        |
|-----------------------|---------|----------------|
| Nitrous acid          | HNO\(_2\)  | \(4.5 \times 10^{-4}\) |
| Hypochlorous acid     | HClO    | \(3.0 \times 10^{-8}\) |

| Base                  | Formula   | \(K_b\)        |
|-----------------------|-----------|----------------|
| Aniline               | C\(_6\)H\(_5\)NH\(_2\) | \(4.3 \times 10^{-10}\) |
| Ammonia               | NH\(_3\)  | \(1.8 \times 10^{-5}\)   |

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 NH\(_4\)Br      | Choose one |
| 0.1 M C\(_6\)H\(_5\)NH\(_3\)Cl | Choose one |
| 0.1 M NaCl            | Choose one |
| 0.1 M KClO            | Choose one |
