Here are the essential concepts you must grasp in order to answer the question correctly.
pH Scale
The pH scale measures the acidity or basicity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity. Each whole number change on the pH scale represents a tenfold change in hydrogen ion concentration, making it crucial for understanding the relative acidity of solutions.

Acidity
Acidity refers to the concentration of hydrogen ions (H+) in a solution. A higher concentration of H+ ions corresponds to a lower pH value, indicating a more acidic solution. Therefore, when comparing solutions, the one with the lower pH value is more acidic, which is essential for determining the relative acidity of solutions A and B.

Comparative Analysis
Comparative analysis involves evaluating two or more items to identify differences and similarities. In the context of pH, it requires comparing the pH values of solutions A and B to determine which is more acidic. This method is fundamental in chemistry for making informed conclusions based on quantitative data.
