Litmus Paper Blue is a pH indicator paper used to detect acidic substances. It is impregnated with litmus dye extracted from lichens, which changes color when exposed to acidic or basic environments. Blue litmus paper turns red under acidic conditions (pH < 4.5) and remains blue in neutral or alkaline solutions. It is widely used in laboratories, education, environmental testing, and industrial processes for quick and easy pH testing.
