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

**2. Rank the following compounds from the least acidic to most acidic; provide a brief explanation.**

**Compounds:**

- **A:** 4-Aminobenzoic acid
- **B:** 4-Nitrophenol
- **C:** 4-Nitrobenzoic acid
- **D:** 4-Aminophenol

**Explanation:**

To rank the acidity of the compounds, consider the functional groups and their influence on acidity:

- **Nitro Group (-NO₂):** Strong electron-withdrawing, increases acidity.
- **Amino Group (-NH₂):** Electron-donating, decreases acidity.
- **Carboxyl Group (-COOH):** Generally acidic.

**Acidic Ranking (from least to most acidic):**

1. **D (4-Aminophenol):** Contains an electron-donating amino group, reducing acidity.
2. **A (4-Aminobenzoic acid):** Carboxyl group is acidic, but aminobenzoic structure is less acidic than nitro groups.
3. **B (4-Nitrophenol):** Phenolic group is moderately acidic, enhanced by the electron-withdrawing nitro group.
4. **C (4-Nitrobenzoic acid):** Combination of a carboxyl group with a nitro group makes this the most acidic due to strong electron-withdrawing effect.

Overall, the presence of the nitro group increases acidity substantially compared to the amino group, and acids (compounds containing -COOH) are generally more acidic than alcohols (-OH).
