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
![### Completing the Acid Dissociation Table for Weak Acids
The table below provides measured acid dissociation constants (\( K_a \)) and \( pK_a \) values of three unknown weak acids. This information is pivotal in understanding the strength of these acids. Remember to ensure each number entered has the correct number of significant digits.
**Table of Acid Dissociation Constants**
| Acid | \( K_a \) | \( pK_a \) | Relative Strength |
|------|--------------------|------------|----------------------|
| A | (input required) | 1.789 | (Choose one) |
| B | 6.2 | (input required) | (Choose one) |
| C | 3.3 x 10^(-4) | (input required) | (Choose one) |
### Instructions:
1. **Fill in the Missing Values**: Use the appropriate formulas and calculations to complete the \( K_a \) and \( pK_a \) values where indicated.
2. **Determine Relative Strength**: Use the provided \( K_a \) and \( pK_a \) values to ascertain the relative strength of each acid. Typically, stronger acids have higher \( K_a \) values and lower \( pK_a \) values.
### Explanation of the Symbols and Graph Elements
- **\( K_a \)**: Acid dissociation constant that quantifies the strength of an acid in a solution.
- **\( pK_a \)**: The logarithmic measure of the acid dissociation constant, calculated as \( pK_a = -\log(K_a) \).
The small in-text box on the right of the table component seems to be a digital input tool involving a checkbox option labeled "×10", a check button, and a reset circle arrow. This may assist users in inputting scientific notation correctly.
### Calculation Examples:
If you need to calculate \( K_a \) or \( pK_a \):
- **\( pK_a \rightarrow K_a \)**:
\[
K_a = 10^{-pK_a}
\]
- **\( K_a \rightarrow pK_a \)**:
\[
pK_a = -\log(K_a)
\]
Using these calculations, you can derive the missing values for each acid based on the information provided. Complete the table accurately and ponder on how \( K_a](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffb7c8d89-d88e-4012-9dce-44cfff81e849%2Ff0b6da0d-2386-4c7c-bc0a-2b2bb494eca2%2Fi1ilaxq_processed.jpeg&w=3840&q=75)
