Question

The pH is a measure of the concentration of the hydrogen ion (H+) in water. Highly acidic water has a very high H+ concentration, while basic water has very low H+ concentrations. The pH scale is a logarithmic scale, such that a difference of one pH unit means a 10-fold difference in H+ concentration. The mathematical relationship between pH and H+ concentration ([H+]) is
pH = –log [H+] OR [H+] = 10-pH where [H+] is in moles per liter.

Use a scientific calculator to calculate [H+] for the following pH values:

7 (a neutral solution)

5.6 (unpolluted rainwater)

3.7 (first acid rain sample in North America)

How many times higher is the concentration of H+ in the Hubbard Brook sample than in unpolluted rainwater?

Answer 1

The hydrogen ion concentration of the following pH samples is as follows:

• 7 (a neutral solution) = 0.845
• 5.6 (unpolluted rainwater) = 0.748
• 3.7 (first acid rain sample in North America) = 0.568

How to calculate hydrogen ion concentration (H+)?

The pH is a measure of the concentration of the hydrogen ion (H+) in water. This means that a relationship exists between H+ and pH of a solution.

The mathematical relationship between pH and H+ concentration ([H+]) is as follows:

pH = –log [H+]

This means that the hydrogen ion concentration (H+) of the following pH values can be calculated thus:

• log 7 (a neutral solution) = 0.845
• log 5.6 (unpolluted rainwater) = 0.748
• log 3.7 (first acid rain sample in North America) = 0.568
