explain acids and bases with litmus paper
Answers
Answer:
The main use of litmus is to test whether a solution is acidic or basic. 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.

Litmus paper is filter paper which has been treated with a natural water-soluble dye obtained from lichens. The resulting piece of paper, called "litmus paper", can be used as a pH indicator..
Litmus Paper---
Litmus paper is commonly used to determine if a solution is acidic or basic. Follow this simple procedure to determine the pH of household chemicals.
litmus paper is made up ofThe primary raw materials used for making litmus paper are wood cellulose, lichens, and adjunct compounds. Litmus paper, as its name implies, is primarily composed of paper. The paper used to make litmus paper must be free of contaminants that could change the pH of the system it is measuring
Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic (i.e. alkaline) conditions. The pigment in blue litmus reacts with H+ ions and changes chemically so the bonds are 'tuned' to reflect a longer wavelength of light to appear red to our eyes.
Litmus solution is extracted from lichens. Lichens are plants belonging to the Thallophyta group. The process of obtaining litmus solution needs the crushing and grinding of lichens. These dyes are then added to neutral water to get the required litmus solution.
