Answer» We will dip the red LITMUS paper in all the three test tubes ONE by one, and stop when it TURNS blue. ... Thereafter , we will take our litmus paper(which is blue now ) and dip it in the rest of the tubes. The TUBE which turns it red CONTAINS an acid while the other contains a neutral solution.
