Which of the following is not a mineral acid?

Options

A. Hydrochloric acid
B. citric acid
C. suphuric acid
D. Nitric acid

Explanation

To determine which of the following is not a mineral acid, we need to first understand what mineral acids are.

### Step 1: Define Mineral Acids
Mineral acids are inorganic acids that release hydrogen ions (H⁺) when dissolved in water. They are typically derived from minerals and include strong acids like hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and nitric acid (HNO₃).

### Step 2: Identify the Given Options
The question presents several options, including:
- HCl (Hydrochloric acid)
- H₂SO₄ (Sulfuric acid)
- HNO₃ (Nitric acid)
- Citric acid

### Step 3: Analyze Each Option
- **HCl**: This is hydrochloric acid, a well-known mineral acid.
- **H₂SO₄**: This is sulfuric acid, another common mineral acid.
- **HNO₃**: This is nitric acid, also classified as a mineral acid.
- **Citric acid**: This is an organic acid found in citrus fruits like lemons and oranges. It does not release H⁺ ions in the same way that mineral acids do.

### Step 4: Conclusion
Since HCl, H₂SO₄, and HNO₃ are all mineral acids, the only option that is not a mineral acid is **Citric acid**.

### Final Answer
**Citric acid is not a mineral acid.**
