A solution with pH= 6 is more acidic than a solution with pH= 4

Answer

To solve the question, we need to understand the relationship between pH and acidity. Here’s a step-by-step breakdown:

### Step 1: Understand the pH Scale
The pH scale ranges from 0 to 14:
- A pH of 7 is considered neutral.
- A pH less than 7 indicates an acidic solution.
- A pH greater than 7 indicates a basic (alkaline) solution.

### Step 2: Compare the Given pH Values
We have two pH values to compare:
- pH = 6
- pH = 4

### Step 3: Determine Acidity Based on pH
Acidity is inversely related to pH:
- Lower pH values correspond to higher concentrations of hydrogen ions (H⁺).
- Therefore, a solution with a lower pH is more acidic.

### Step 4: Analyze the Given Statement
The statement claims that a solution with pH 6 is more acidic than a solution with pH 4. However:
- Since pH 4 is lower than pH 6, it indicates that the solution with pH 4 has a higher concentration of hydrogen ions and is therefore more acidic.

### Step 5: Conclusion
The statement is false. A solution with pH 6 is less acidic than a solution with pH 4.

### Final Answer
A solution with pH 6 is **not** more acidic than a solution with pH 4; it is less acidic.
