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.
![**Problem Statement:**
Calculate the pH and concentrations of CH₃NH₂ and CH₃NH₃⁺ in a 0.0407 M methylamine (CH₃NH₂) solution. The Kb of CH₃NH₂ is 4.47 × 10⁻⁴.
**Solution Fields:**
- **pH =** [Enter calculated value here]
- **[CH₃NH₂] =** [Enter calculated concentration here] M
- **[CH₃NH₃⁺] =** [Enter calculated concentration here] M
**Explanation:**
To solve this problem, you will need to:
1. Use the given Kb value for methylamine to find the concentrations of CH₃NH₂ and CH₃NH₃⁺.
2. Apply the formula for base dissociation to determine the hydroxide ion (OH⁻) concentration.
3. Convert the OH⁻ concentration to pH.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8bdaded0-401d-48e8-a8ea-1a7ee4f60f02%2F908ed966-b8b1-4f3e-82f9-6a6c0ffd76d1%2Fdisv95t_processed.png&w=3840&q=75)
