actually none of them is an acid. litmus paper is an indicator used to detect whether a substance is acid or basic.now it turns blue if there is a base and red in case of acid. similarly phenolphethien and methyl orange are also indicators. and digene is a base used as antacid in case of access of acid in stomach or we can say acidity

None of them are acids, but they can exist in acidic solution.
The only difference in them and their acidic solutions is that their colour can change.
Hope this helps :D
