You have two solutions, A and B. The pH of solution A is 6 and pH of solution B is 8. Which solution has more hydrogen ion concentration? Which of this is acidic and which one is basic?

We can use the rule to find the hydrogen ion concentration which states that, “The pH of any solution is inversely proportional to the hydrogen ion concentration” i.e, the solution that has a lower pH number will have a higher hydrogen ion concentration. Hence, solution A will have a higher hydrogen ion concentration than solution B.
Also the solution with pH below 7 shows acidic behaviour hence solution A is acidic and that for solution B it is greater than 7 so it’s a basic solution.
