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.
![A 1.80 M solution of an unknown acid has a pH of 1.22. What is the Ka?
**Your Answer:**
[Text Box for Answer]
---
To solve for the \( K_a \) of the acid, use the relationship between pH, hydrogen ion concentration, and \( K_a \):
1. **Find the concentration of hydrogen ions \([H^+]\):**
\[
[H^+] = 10^{-\text{pH}} = 10^{-1.22}
\]
2. **Write the expression for \( K_a \):**
\[
K_a = \frac{[H^+][A^-]}{[HA]}
\]
where \([HA]\) is the initial concentration of the acid minus \([H^+]\), and \([A^-] = [H^+]\).
3. **Substitute the values:**
\[
K_a = \frac{(10^{-1.22})^2}{1.80 - 10^{-1.22}}
\]
Calculate the above to find \( K_a \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb9b814ac-1a5f-4504-b547-b7326372e811%2F79154e24-77bd-4d30-b050-c1d5f3668cde%2Fuy3yevx_processed.jpeg&w=3840&q=75)
For a weak acid the relationship between dissociation constant and concentration of H+ ions is
[H+] =
C = concentration of acid
Ka = dissociation constant of acid
