.you are provided with 3 liquids in 3 different test tubes one is distilled water and other

the 3 liquids?
Answers
Explanation:
3 liquids are there. One is acid and the other is base and the last one is distilled water and you are given red litmus paper.
In these three in which liquid litmus paper turns red to blue that is a base.
Then two liquids are left. In these two in which liquid litmus paper turns from blue to red that is acid.
Which is left that is distilled water.
From this question we get to know that,
Litmus paper when dipped in acid turns from blue to red.
Litmus paper when dipped in base it turns from red to blue.
Litmus paper when dipped in neutral there is no colour change.
Answer:
in the question 1 is distilled water
to identity the 2 if the red litmus changes into blue that is a base if not then it is acid a d to find 3 we have to repeat this process
