particular type of acid-base indicator isa universal indicator, which is a mixture of multiple indicators that gradually changes color over a wide pH range. The indicators are chosen so mixing a few drops with a solution will produce a color that can be associated with an approximate pH value...
phenolphthalein- a laxative used in many preparations under various trade names; also used as an acid-base indicator in titrations involving weak acids and strong bases because it is brilliant red at high alkalinity and colorless below pH 8 ...
14. A low pH value indicates acidity, a pH of 7 is neutral, and a high pH value indicates alkalinity. The pH value can tell you whether you're dealing with anacid or a base, but it offers limited value indicating the truestrengthof the acid. The formulas to calculate pH and pOH ...
