Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffb7c8d89-d88e-4012-9dce-44cfff81e849%2F816e3166-ff7e-4d2e-bcde-3308e53740ff%2Fpb92z6h_processed.jpeg&w=3840&q=75)
