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.
![**Solution Details:**
A solution contains **0.302 M ammonium bromide** and **0.201 M ammonia**.
**Objective:**
Determine the pH of this solution.
---
To calculate the pH of a solution containing both ammonium bromide and ammonia, apply the Henderson-Hasselbalch equation, which is used for buffer solutions containing a weak base and its conjugate acid. Ammonia (NH₃) is the weak base, and ammonium bromide (NH₄Br) provides the conjugate acid (NH₄⁺).
The equation is:
\[ \text{pH} = \text{pK}_a + \log \left(\frac{[\text{base}]}{[\text{acid}]}\right) \]
Where:
- \([\text{base}]\) is the concentration of ammonia (0.201 M).
- \([\text{acid}]\) is the concentration of ammonium bromide (0.302 M).
- \(\text{pK}_a\) is the negative logarithm of the acid dissociation constant of the ammonium ion.
This setup allows for the calculation of the pH to understand the acidity/basicity of the solution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F16140577-95fc-4112-8b0a-8e4365545066%2Fbac5348c-d4a1-4ab6-b762-365701862f21%2Fcpoxim_processed.png&w=3840&q=75)
