| Abstract: | The article introduces a method of the pigment abstracted from radish, cabbage, comfrey, sappan wood, roselle, petunia and used as acid-alkali indicator. The change of colour at different pH ranges in plant pigments was measured. Then the plant acid-alkali indicator was used in colour indication of some common acid, alkali and salt solutions , and the approving effect was gotten. On the basis of study, some noticeable questions in making plant indicator by self were pointed. |
