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:**
The value of \(K_a\) for nitrous acid is \(4.50 \times 10^{-4}\).
What is the value of \(K_b\), for its conjugate base, \(NO_2^-\)?
**Answer:**
To find the value of \(K_b\) for the conjugate base \(NO_2^-\), we can use the relationship between the acid dissociation constant (\(K_a\)) and the base dissociation constant (\(K_b\)) for a conjugate acid-base pair, which is given by:
\[ K_a \times K_b = K_w \]
where \(K_w\) is the ion-product constant for water. At 25°C, \(K_w\) is \(1.0 \times 10^{-14}\).
Given:
\[ K_a = 4.50 \times 10^{-4} \]
We need to find \(K_b\):
\[ K_b = \frac{K_w}{K_a} \]
\[ K_b = \frac{1.0 \times 10^{-14}}{4.50 \times 10^{-4}} \]
\[ K_b = 2.22 \times 10^{-11} \]
Thus, the value of \(K_b\) for the conjugate base \(NO_2^-\) is \(2.22 \times 10^{-11}\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fad75d3c3-f925-415c-aa85-2c90219f0688%2F4105d578-b33f-4eac-9668-5bb800fec477%2Fu5oetwo_processed.png&w=3840&q=75)
