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.
![**Hydronium Ion Concentration and pH Calculation of \( \text{HNO}_3 \) Solution**
### Problem Statement
What is the hydronium ion concentration of a 0.0020 M solution of \( \text{HNO}_3 \) (Nitric Acid)?
**Concentration = [ ] M**
What is its pH?
**pH = [ ]**
### Discussion
To calculate the hydronium ion concentration and pH of the given nitric acid solution, you can use the following steps:
1. **Determine the Hydronium Ion Concentration:**
Since \( \text{HNO}_3 \) is a strong acid, it completely dissociates in water. This means the concentration of hydronium ions (\( \text{H}_3\text{O}^+ \)) is equal to the initial concentration of the acid.
\[ [\text{H}_3\text{O}^+] = [\text{HNO}_3] = 0.0020 \, M \]
2. **Calculate the pH:**
pH is calculated using the formula:
\[ \text{pH} = -\log [\text{H}_3\text{O}^+] \]
Substituting the known concentration:
\[ \text{pH} = -\log(0.0020) \]
\[ \text{pH} \approx 2.70 \]
### Conclusion
The hydronium ion concentration of a 0.0020 M \( \text{HNO}_3 \) solution is \( 0.0020 \, M \), and its pH is approximately 2.70.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F883e3e80-624e-4e0d-88a1-3570ac65b326%2F1bcf8076-0296-482e-adf0-95fbe206f866%2F3cf2uh2_processed.png&w=3840&q=75)
