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
<h3>How to calculate hydrogen ion concentration (H+)?</h3>
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
