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 12
**In the aqueous reaction below, the acid reactant is \_\_\_\_\_\_ and its conjugate base product is \_\_\_\_\_\_:**
\[ \text{CH}_3\text{NH}_2 + \text{HSO}_4^- \leftrightarrow \text{CH}_3\text{NH}_3^+ + \text{SO}_4^{2-} \]
- a. **CH3NH2; CH3NH3+**
- b. **CH3NH2; SO4^{2-}**
- c. **HSO4^-; CH3NH3+**
- d. **HSO4^-; SO4^{2-}**
- e. **HSO4^-; H3O+**
In this multiple-choice question regarding the identification of the acid reactant and its conjugate base product in an aqueous reaction, the possible options are listed from a to e. The chemical reaction given is between methylamine (CH₃NH₂) and bisulfate ion (HSO₄⁻), resulting in the formation of methylammonium ion (CH₃NH₃⁺) and sulfate ion (SO₄²⁻).
**Detailed Explanation:**
- **Acid Reactant:** In this context, the acid reactant is the species that donates a proton (H⁺). Here, HSO₄⁻ donates a proton to CH₃NH₂.
- **Conjugate Base Product:** The conjugate base is formed when an acid loses a proton. After HSO₄⁻ donates a proton, it becomes SO₄²⁻.
Therefore, the correct answer should be identified based on the above definitions and the given options.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc31825ca-e532-4346-8c67-c6f0bc8ad95c%2F2ddfad27-6b80-4698-a6dc-279c0968b05c%2F0jp7se_processed.jpeg&w=3840&q=75)
