Answer:
Explanation:
Lichens provide the litmus solution. To make a litmus solution, a natural dye derived from lichens is dissolved in distilled water.
Litmus is mostly used to determine if a solution is acidic or basic. The color shift occurs over the pH range 4.5–8.3 at 25 °C (77 °F), with light-blue litmus paper turning red under acidic conditions and red litmus paper turning blue under basic or alkaline settings. Purple litmus paper is neutral. Water-soluble gases that change acidity or basicity can also be tested with wet litmus paper; the gas dissolves in the water and the resulting solution colors the litmus paper.
