Litmus Paper Red India (100 Strips)
Red Litmus Indicators or Litmus Paper is most used in chemical laboratory in Bangladesh. Basically used in School, College, University Laboratory.
Red Litmus is a water-soluble mixture of different dyes extracted from lichen. Dyeing filter paper either red or blue with this ink creates one of the oldest forms of testing alkalinity and acidity. Red litmus paper turns blue under alkaline conditions. Sold in boxes of 100 strips of paper. Made in India.
Litmus is a water-soluble mixture of different dyes extracted from lichens. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity.The main use of litmus is to test whether a solution is acidic or basic, as blue litmus paper turns red under acidic conditions, and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple.[2] Wet litmus paper can also be used to test for water-soluble gases that affect acidity or basicity; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, turns red litmus paper blue. While all litmus paper acts as pH paper, the opposite is not true.
Litmus can also be prepared as an aqueous solution that functions similarly. Under acidic conditions, the solution is red, and under alkaline conditions, the solution is blue.
Chemical reactions other than acid–base can also cause a color change to litmus paper. For instance, chlorine gas turns blue litmus paper white; the litmus dye is bleached[3] because hypochlorite ions are present. This reaction is irreversible, so the litmus is not acting as an indicator in this situation.

Litmus is a crucial tool in the laboratory setting, offering indispensable features for various scientific applications. Its versatility lies in its ability to test acidity or alkalinity of substances through color changes. Litmus paper, one of its essential products, comes in red and blue variants, each indicating different pH levels. Additionally, Litmus solutions offer precise pH measurements across a broader spectrum. These solutions can be used for titrations and qualitative analysis. Litmus strips, another popular product, provide quick, convenient pH testing for a range of substances. With its reliability and ease of use, Litmus products are fundamental for researchers, educators, and professionals in fields such as chemistry, biology, and environmental science.
