pH Indicator Ranges
Solutions of pH indicators have a certain color at certain pH levels and this color changes with change in pH of the solution. These indicators are used to visually identify the acidity or alkalinity of the solution. pH indicators generally change color over a range of two pH units and work only in solutions in which a color change can be observed and can give only an approximate pH value. The table below gives a list of the common laboratory pH indicators.
