Theory of indicator there are two common methods for determining the double indica tor in the titration of alkali mixture eg. In the acid-base titration, the equivalence point is known with the help of indicator which changes its color at the end point in the titration of the polyacidic base or polybasic acid there are more than one endpoint one indicator is not able to give color change at every endpoint so, to find. Double titration the method involves two indicator (indicators are substances that change their colour when a reaction is complete) phenolphthalein and methyl orange.
A titration involves the gradual addition of a titrant solution to a solution known as an analyte the titrant in a titration has a known concentration, whereas the analyte has an unknown concentration of some compound in order to determine carbon dioxide levels in a solution, you can titrate it.
