Webb26 jan. 2024 · pH is a measure of the concentration of hydronium (H 3 O +) ions in an aqueous solution. It is measured on a negative logarithmic scale from 0 to 14. Acidic solutions are below pH 7, with 0 being the most acidic. Basic solutions are above pH 7, with 14 being the most basic. A solution with a pH of 7 is considered neutral. WebbThe pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
