However, alkaline water with a pH level of 9 or higher may taste bitter. The pH level of water can also change the taste of anything you use it in, like coffee or tea.

Solutions can be acidic, alkaline or neutral. For example, pure water is neutral with a pH of 7. A solution of common salt (sodium chloride) is also neutral, so it has a pH of 7 too.

Just as an example, a substance with a pH of 4 on the scale is 3 points down from water with a pH of 7. On the logarithmic scale, this means a difference of 10 3 or 1000.
