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.
Q6
![**Title: Determining the pH of a Pyruvic Acid Solution**
**Question:**
What is the pH of a solution that contains 1 part pyruvic acid and 4 parts pyruvate? The pKa for pyruvic acid is 2.50.
**Options:**
- 1.90
- 2.40
- 2.60
- 3.10
**Explanation:**
To determine the pH of this solution, you can use the Henderson-Hasselbalch equation:
\[ \text{pH} = \text{pKa} + \log\left(\frac{\text{[A}^- \text{]}}{\text{[HA]}}\right) \]
Where:
- \([A^-]\) is the concentration of the conjugate base (pyruvate)
- \([HA]\) is the concentration of the acid (pyruvic acid)
Given:
- \([A^-] = 4\) parts
- \([HA] = 1\) part
- \(\text{pKa} = 2.50\)
\[ \text{pH} = 2.50 + \log\left(\frac{4}{1}\right) \]
\[ \text{pH} = 2.50 + \log(4) \]
\[ \text{pH} = 2.50 + 0.60 \]
\[ \text{pH} = 3.10 \]
Thus, the correct answer is 3.10.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2b8d26a8-87eb-4d55-9239-418c1bd04690%2Ff4db7283-c080-467b-9b7f-7087d997f416%2F4qd7cl9_processed.jpeg&w=3840&q=75)
