WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

This scale is logarithmic, so there is a 10-fold difference in strength between each number. Pure water is neutral, neither an acid nor base. As such, it sits smack in the middle of the pH scale at 7. But mix an acid with water and the water molecules will act as bases.

WebMay 6, 2024 · The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline. A pH level of 7.0 at 25°C is defined as "neutral" because the concentration of H 3 O + equals the concentration of OH − in pure water.
