They're classified according to their pH level.
Substances that are not acidic or alkaline are neutral in their pH. Lots of substances exhibit a slight variance from a pH of 7, which is neutral. We don't notice many of them because they aren't far from neutral.
It depends where the water comes from and what substances are dissolved in it. It's often nearly neutral, but can vary from about 6.5 (slightly acidic) to about 9.5 (alkaline), according to the World Health Organisation.
acidic n neutral
The compounds that are neutral in nature have a pH of 7. These substances are neither acidic nor basic.
acidic
No. Hydrogen, H2, is neutral. H+ ions are acidic.
Substances that are not acidic or alkaline are neutral in their pH. Lots of substances exhibit a slight variance from a pH of 7, which is neutral. We don't notice many of them because they aren't far from neutral.

Acidic substances will lower pH and more alkaline or basic substances will put it above the neutral value of pH = 7
acidic n neutral
The compounds that are neutral in nature have a pH of 7. These substances are neither acidic nor basic.
The pH number determines if the substance is acidic or basic. Numbers 1-6 determine acidic substances, 1 being the most acidic. Numbers 8-14 determine basic substances, 14 being the most basic. 7 is neutral. (:
