Question
**Acids and Bases: Interconverting \( K_a \) and \( pK_a \)** **Instruction:** Complete the following table, which lists information about the measured acid dissociation constants of three unknown weak acids. **Note:** Be sure each number you put in the table has the correct number of significant digits. | Acid | \( K_a \) | \( pK_a \) | Relative Strength | |------|-------------------|------------|-------------------| | A | \(\square\) | 7.9 | (Choose one) | | B | \(\square\) | 1.142 | (Choose one) | | C | \(2.8 \times 10^{-9}\) | \(\square\) | (Choose one) | **Options for Relative Strength:** - Strongest - Intermediate - Weakest **Interface Elements:** - A box for entering \( K_a \) value - A calculator symbol indicating multiplicative inputs for scientific notation **Buttons:** - **Explanation**: Provides detailed explanation of the concepts. - **Check**: Validates the entered values. --- The task is to determine the \( K_a \) values for acids A and B and the \( pK_a \) for acid C. Subsequently, you must select the appropriate relative strength of each acid based on their dissociation constants.

Expert Solution
Step 1: Determine the relative strength order of the acids from the given data:

Given,

                  acid                Ka                pKa     relative strength
                    A                 box enclose space space end enclose                7.9                   
                   B                 box enclose space space end enclose             1.142                
                   C          2.8 x 10-9                box enclose space space end enclose
