Question
**Complete the table below by filling in the missing information regarding the measured acid dissociation constants of three unknown weak acids.**

**Note:** Ensure each number you enter in the table has the correct number of significant digits.

| acid | \( K_a \)               | \( pK_a \) | relative strength |
|:----:|:----------------------:|:---------:|:-----------------:|
|  A   | \( 2.11 \times 10^{-1} \) |           | (Choose one) \[dropdown menu\] |
|  B   |                        |  5.6      | (Choose one) \[dropdown menu\] |
|  C   | \( 3.5 \times 10^{-3} \)   |          | (Choose one) \[dropdown menu\] |

- There are two empty fields under \( pK_a \) for acids A and C.
- There is one empty field under \( K_a \) for acid B.
- Each row includes a dropdown menu to select the relative strength of each acid.

To complete the table, calculate the respective \( pK_a \) values where needed using the formula \( pK_a = -\log K_a \) and \( K_a \) where \( K_a = 10^{-pK_a} \) as appropriate. Then choose the correct relative strength from the dropdown menu.

**Explanation of the Diagram:**

The diagram on the right side of the table shows a simple interface for entering or calculating the provided values. This interface includes:
- A small checkable box labeled "×10".
- An empty field for numerical input.
- Two additional buttons: One with an "X" for possibly clearing the input and another with a circular arrow, likely for resetting the form to its original state.
