### Weak Acids and Weak Bases Data Overview

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

#### Weak Acids:
| **Name**          | **Formula**  | **Ka**          |
|-------------------|--------------|-----------------|
| Acetic Acid       | HCH₃CO₂      | 1.8 × 10⁻⁵      |
| Hydrocyanic Acid  | HCN          | 4.9 × 10⁻¹⁰     |

#### Weak Bases:
| **Name**  | **Formula**      | **Kb**          |
|------------|------------------|-----------------|
| Aniline    | C₆H₅NH₂         | 4.3 × 10⁻¹⁰     |
| Ammonia    | NH₃             | 1.8 × 10⁻⁵      |

### pH Ranking Task:

Using this data, 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 NH₄Cl              | [ Dropdown: 1 (lowest), 2, 3, 4 (highest) ] |
| 0.1 M NaCN               | [ Dropdown: 1 (lowest), 2, 3, 4 (highest) ] |
| 0.1 M KCl                | [ Dropdown: 1 (lowest), 2, 3, 4 (highest) ] |
| 0.1 M C₆H₅NH₃Br          | [ Dropdown: 1 (lowest), 2, 3, 4 (highest) ] |

### Explanation of Data Tables:
- **Ka (Acidity constant)**: A measure of the strength of a weak acid in solution. The smaller the Ka value, the weaker the acid.
- **Kb (Basicity constant)**: A measure of the strength of a weak base in solution. The smaller the Kb value, the weaker the base.

### Solution Ranking Logic:
- Solutions with species that do not hydrolyze (e.g., KCl) typically have neutral pH
