Indikatorer används i titrering när man till exempel ska bestämma en lösnings buffertförmåga. pH Indicators. Intracellular pH is generally between ~6.8 and 7.4 in the cytosol and ~4.5 and You’ll notice in the graphic above that the different indicators have different ‘ranges’ – pH numbers over which they gradually change colour. This makes them useful for different reactions between acids and bases, which have different equivalence points; these are usually carried out as titrations , so the exact amount of one reactant added to the other can be monitored. För att mäta pH används indikatorer. Det finns flera olika slags indikatorer.
