Consider the pH value of the following acidic samples :
| S. No. | Sample | pH Value |
|---|---|---|
| 1. | Lemon Juice | 2.2 |
| 2. | Gastric Juice | 1.2 |
| 3. | Vinegar | 3.76 |
| 4. | Dil. Acetic acid | 3.0 |
The decreasing order of their H+ ion concentration is
- 3 > 4 > 1 > 2
- 2 > 1 > 3 > 4
- 2 > 1 > 4 > 3
- 3 > 4 > 2 > 1

Answer
2 > 1 > 4 > 3
Reason — The number of H+ ion concentration determines the acidic strength of the sample. The pH and hydrogen ion concentration are inversely related i.e., as the value of pH increases, the H+ ion concentration decreases hence decreasing order of their H+ ion concentration is 2 > 1 > 4 > 3.
