Tap water has a pH of about 5 or 6, showing that it is very weakly acidic. This is usually explained by the presence of dissolved carbon dioxide in the tap water.

The pH is calculated as the negative logarith of the H+ concentration. So if your pH is 7.4, the Concentration of your H+Ions is ten to the power of minus 7.4 = 0.00000074 mole/liter.
The higher your H+ concentration, the lower your pH, meaning the more acidic it is. A pH of zero is the strongest acid with an H+ concentration of 1mole/liter (calculated as 10 to the power of zero = 1).

pH and H+ concentration are inversely prportional, which means the higher the pH the lower the H+ concentration and vice versa. The more hydrogen ions (H+) in a liquid the more acidic it is.

water is supposed to be neutral on the pH scale, right?

[H+]=10^(-pH)
