The human olfactory system contains about 1,000 olfactory receptors. This is considered as the largest gene family which only a human possess. The number seems so large but not all of the 1,000 are functional. There’s only about 350 working olfactory receptors in humans.

The pH is a measure of the concentration of the hydrogen ion (H+) in water. Highly acidic water has a very high H+ concentration
LUCKY_DIMON [66]

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
