WebbA solution of a strong acid at concentration 1 M (1 mol/L) has a pH of 0. A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base Webb26 apr. 2024 · The pH scale measures how acidic or alkaline a substance is. It runs from 0 to 14, with a pH of 7 being neutral, a pH lower than 7 being acidic and a pH higher than 7 being alkaline. The scale is logarithmic, meaning each whole pH value below 7 is ten times more acidic than the next higher value.
