**Solution:**
**pH Scale:**
The pH scale is used to measure the acidity or alkalinity of a solution. It ranges from 0 to 14, with 7 being considered neutral. Solutions with pH values below 7 are considered acidic, while solutions with pH values above 7 are considered alkaline or basic.
**Explanation:**
In this case, we are comparing a solution with pH 5 to a solution with pH 3 to determine which one is more acidic.
**pH 5 Solution:**
A solution with pH 5 is acidic because it is below the neutral pH of 7. However, it is less acidic compared to a solution with pH 3.
**pH 3 Solution:**
A solution with pH 3 is also acidic because it is below the neutral pH of 7. However, it is more acidic compared to a solution with pH 5.
**Comparing pH Values:**
The pH scale is logarithmic, which means that each whole number change in pH represents a tenfold change in acidity. In other words, a solution with pH 3 is ten times more acidic than a solution with pH 4, and a hundred times more acidic than a solution with pH 5.
Therefore, we can conclude that a solution with pH 3 is more acidic compared to a solution with pH 5.
**Conclusion:**
In summary, a solution with pH 3 is more acidic compared to a solution with pH 5. The pH scale is logarithmic, and each whole number change represents a tenfold change in acidity. Therefore, a solution with pH 3 is ten times more acidic than a solution with pH 4, and a hundred times more acidic than a solution with pH 5.
