WebThe pH scale is an indication of the hydrogen ion concentration and runs from below 0 to above 14. Acidic solutions have a higher concentration of H⁺(aq) ions than OH⁻(aq) and have a pH below 7. Alkaline solutions have a higher concentration of OH⁻(aq) ions than H⁺(aq) ions and have a pH above 7. WebMar 5, 2024 · pH A measure of a solution’s acidity or alkalinity. A pH of 7 is perfectly neutral. Acids have a pH lower than 7; the farther from 7, the stronger the acid. Alkaline solutions, called bases, have a pH higher than 7; again, the farther above 7, the stronger the base.
