WebpH compares the acidity or alkalinity of a solution at a given temperature. A pH of 7 describes a neutral solution because the activities of hydrogen and hydroxide ions are equal. When the pH is below 7, the solution is described as acidic—the hydrogen ion activity increases and the pH value decreases. WebMay 14, 2024 · Basically pH is a measure of how acidic or basic a liquid is with the range from 0 to 14. The measurement of less than 7 indicates that the liquid is acidic, 7 being …
