Which one is the strongest acid

Options

A. HClO
B. `HClO_(2)`
C. `H_(2)SO_(4)`
D. `HClO_(4)`

Explanation

To determine which one is the strongest acid among the given options, we can follow these steps:

### Step 1: Identify the Acids
List the acids provided in the question. For this solution, we will consider one of the acids mentioned in the transcript: \( \text{HClO}_4 \) (Perchloric acid).

### Step 2: Understand Acid Strength
The strength of an acid is determined by its ability to donate protons (H+ ions). Stronger acids have more stable conjugate bases after they donate a proton.

### Step 3: Analyze the Conjugate Base
When \( \text{HClO}_4 \) donates a proton, it forms its conjugate base \( \text{ClO}_4^- \). The stability of this conjugate base is crucial in determining the strength of the acid.

### Step 4: Evaluate Conjugate Base Stability
The conjugate base \( \text{ClO}_4^- \) has a structure where the negative charge is delocalized over four oxygen atoms. This delocalization stabilizes the conjugate base significantly.

### Step 5: Compare with Other Acids
To conclude that \( \text{HClO}_4 \) is the strongest acid, we must compare it with other acids. If other acids have less stable conjugate bases than \( \text{ClO}_4^- \), then \( \text{HClO}_4 \) is indeed the strongest.

### Conclusion
Based on the analysis, \( \text{HClO}_4 \) is the strongest acid among the options due to the stability of its conjugate base \( \text{ClO}_4^- \).

### Final Answer
The strongest acid is \( \text{HClO}_4 \) (Perchloric acid).
