WebSep 15, 2024 · In simple terms, pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid. What happens when the pH increases? The logarithmic scale of pH means that as pH increases, the H+ concentration will decrease by a power of 10. WebKEY CONCEPT - Acidic solutions contain higher concentrations of H+ ions than pure water and have pH values below 7. Basic, or alkaline, solutions contain lower concentrations of H+ ions than pure water and have pH values above 7. You can compare EITHER the hydrogen ion (H+) and hydroxide ion (OH-) concentrations to compare the two.
