they do not get out of order as from time to time do the pH-meters. Four buffers (Acetate buffer‚ phosphate buffer‚ ammonium buffer and an unknown solution) were tested with eight different indicators. The method employs the use of complex organic dyes which change to distinctive colors through a specific pH range of the buffer solutions giving the acid and base color that was used in identifying the pH range. The obtained result of each group is relatively close to the theoretical results. The outcome
