Question

What is the concentration of H* ions at a pH = 2? I mol/L Ht ions increase in concentration at lower pH values. Calculate how many more Htions there are in a solution at a pH = 2 than in a solution at a pH = 6. Find the concentration of H+ ions at a pH = 2 and at a pH = 6 in Table B. Then divide the concentration of H+ ions at a pH = 2 by the of H+ ions at a pH = 6. Record your answer in Table C. What is the concentration of Htions at a pH = 6? mol/L How many more Hions are there in a solution at a pH = 2 than in a solution at a pH = 6?​

Answer 1

The concentration of H+ ions at a pH of 2 is 1 x 10^-2 M. The concentration of H+ ions at a pH of 6 is 1 x 10^-6 M. Therefore, there are 10,000 more H+ ions in a solution at pH 2 than at pH 6.

Step-by-step explanation:

The concentration of hydronium ions, H+, at a pH of 2 can be calculated using the equation pH = -log[H+]. Therefore, pH of 2 indicates the concentration of H+ ions is 1 x 10-2 M.

To calculate the concentration of H+ ions at a pH of 6, we use the same equation. pH of 6 indicates the concentration of H+ ions is 1 x 10-6 M.

To find the difference in concentration, we divide the concentration at pH 2 by the concentration at pH 6: (1 x 10-2 M) / (1 x 10-6 M) = 10,000.
