Which of the following can form more than one acid salt?

Options

A. `CH_(3)COOH`
B. `H_(3)PO_(4)`
C. `CH_(3)CH_(2)COOH`
D. `ZnO`

Explanation

It seems there was a mix-up with the video transcript provided, as it does not relate to the chemistry question regarding acid salts. However, I can provide a step-by-step solution to the question: "Which of the following can form more than one acid salt?"

### Step-by-Step Solution:

1. **Understand Acid Salts**: Acid salts are formed when a part of the acid is replaced by a metal or ammonium ion. They can be derived from polyprotic acids, which can donate more than one proton (H⁺ ion).

2. **Identify Polyprotic Acids**: Look for acids that can donate more than one proton. Common examples include sulfuric acid (H₂SO₄), phosphoric acid (H₃PO₄), and carbonic acid (H₂CO₃).

3. **List Possible Acid Salts**:
- **Sulfuric Acid (H₂SO₄)**: Can form hydrogen sulfate (HSO₄⁻) and sulfate (SO₄²⁻) salts.
- **Phosphoric Acid (H₃PO₄)**: Can form dihydrogen phosphate (H₂PO₄⁻), hydrogen phosphate (HPO₄²⁻), and phosphate (PO₄³⁻) salts.
- **Carbonic Acid (H₂CO₃)**: Can form bicarbonate (HCO₃⁻) and carbonate (CO₃²⁻) salts.

4. **Conclusion**: Based on the above analysis, sulfuric acid, phosphoric acid, and carbonic acid can all form more than one acid salt.

5. **Final Answer**: The acids that can form more than one acid salt are sulfuric acid (H₂SO₄), phosphoric acid (H₃PO₄), and carbonic acid (H₂CO₃).
