Mechanism of an Universal Indicator
An universal indicator is collectively a mixture of indicators which show a color change in a solution,which interprets how acidic or basic a solution is. A universal indicator can be in paper form or present in a form of a solution.
 * Paper form: Is a strip of colored paper which changes color to red if the solution is acidic and to blue if the solution is basic. The strip can be placed directly onto a surface of a wet substance or few drops of the solution can be dropped onto the universal indicator using a dropping equipment. If the test solution is in dark color, it is preferable to use paper universal indicator.
 * Solution: The main components of an Universal indicator, in the form of a solution, are thymol blue, methyl red, bromothymol blue and phenolphthalein. This mixture is important because, each component, losses or gains electrons depending upon the acidity or basicity of the solution being tested. It is beneficial to use this type of an universal indicator in a colorless solution. This is will increase the accuracy of indication.
