How to measure pH?
How pH Is Measured 1 The most common method is a pH meter, which involves a pH-sensitive electrode (usually made of glass) and a reference electrode. 2 Acid-base indicators change color in response to different pH values. Litmus paper and pH paper are used for quick, relatively imprecise measurements. These are strips of paper that have been treated with an indicator. 3 A colorimeter may be used to measure the pH of a sample. A vial is filled with a specimen and a reagent is added to produce a pH-dependent color change. The color is compared against a chart or standard to determine the pH value.
What is the pH of a solution?
pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic. pH of 7 is considered neutral (e.g., pure water). Typically, values of pH range from 0 to 14, although very strong acids may have a negative pH, while very strong bases may have a pH exceeding 14.
