Litmus Paper and the Litmus Test. This litmus test uses red, blue, or purple litmus paper to determine whether a sample is acidic, basic, or neutral. Litmus paper is pH indicator made by treating filter paper with a solution of litmus. Litmus, in turn, is mixture of dyes made from lichens that changes color in response to acids (red) or bases.. Step-1: Take the unknown solution in the beaker. Step-2: Take a strip of purple litmus paper or red litmus paper both are suitable. Step-3: Now, dip the tip of the litmus paper in the respective solution. If the purple litmus paper or red litmus paper turns blue, then the given solution is basic. Red Litmus Paper Dipped in Base.
