Litmus is a water-soluble mixture of natural dyes derived from certain species of lichens, particularly Roccella tinctoria and Lecanora tartarea. The term “litmus” originates from an old Norse word that denotes “dye-using moss.” It is a widely used compound for qualitative pH testing and is commonly used in chemistry laboratories, educational settings, and various industries to quickly assess whether a solution is acidic or alkaline.
