Question

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?

Answer 1

A pH value of less than 7 indicates an acidic solution, while greater than 7 indicates a basic solution. Therefore, the solution with pH = 6 is acidic and has more hydrogen ion concentration than the solution of pH = 8 which is basic.

Answer 2

pH of solutions, A = 6

∴ H⁺ ion concentration = 10^-6 M.

pH of solution B = 8.

∴ H⁺ ion concentration = 10^-8 M.

As 10^-6>10^-8, hence solution A has more H⁺ ion concentration.

A solution with pH < 7 is acidic. Hence, solution A is acidic.

A solution with pH > 7 is basic. Hence, solution B is basic.
