Answer 1

Explanation:The pH value indicates the acidic and basic nature of a solution. The pH value of less than 7 indicates an acidic solution while greater than 7 indicates a basic solution. The pH value of a neutral solution is 7. Thus, in this case, the solution A with pH=6 is acidic and has more hydrogen ion concentration than the solution B (pH=8) which is basic.
