Solution A, with a pH of 6, has a higher hydrogen ion concentration and is acidic. Solution B, with a pH of 8, has a lower hydrogen ion concentration and is basic.
Explanation:
pH and Hydrogen Ion Concentration: The pH scale is a logarithmic scale that measures the acidity or basicity of a solution. A lower pH indicates a higher hydrogen ion concentration (H+), which means it’s more acidic. A higher pH indicates a lower hydrogen ion concentration and a more basic solution.
Acidic vs. Basic: A pH below 7 is considered acidic, while a pH above 7 is considered basic.
Comparing Solutions A and B: Since solution A has a pH of 6 (less than 7), it is acidic and has a higher hydrogen ion concentration than solution B, which has a pH of 8 (more than 7) and is basic.
