Explanation:
In acid - If the strip of red will be dipped in acid then it's colour will be RED so it can be identified as acid.
OR
it's taste will be sour.
But some acid can't be tasted since the questions say only acid substance then either of 2 ways can work.
In base- the strip when dipped to base will turn it's colour to red thus it will indicate it's base.
OR
it's taste will be bitter.
In neutral- The strip when dipped in neutral solution then it will turn purple thus it will indicate it's purple.
Hope it helps!!!
