Naoh litmus color
WitrynaThe equivalence point for the titration of HCl with NaOH occurs within the color change of litmus. The pH of the equivalence point for the titration of CH3CO2H with NaOH … WitrynaThe litmus colour change happens over an unusually wide range, but it is useful for detecting acids and alkalis in the lab because it changes colour around pH 7. Methyl orange or phenolphthalein would be less useful. This is more easily seen diagramatically. For example, methyl orange would be yellow in any solution with a pH greater than 4.4.
