Common Acid-Base Indicators Several acid-base indicators are listed below, some more than once if they can be used over multiple pH ranges. The quantity of indicator inaqueous(aq.) or alcohol (alc.) solution is specified. Tried-and-true indicators include thymol blue, tropeolin OO, methyl ...
1、indicatorsmaterials which change colour according to ph of solution in which they are placed.litmus, methyl orange ,phenolpthalein are examples.red cabbage and blackberry juice contain natural indicators.most indicators are weak acidshin h+ + in- red blue(acid) (base)add acid.what happens?
