Litmus is a natural dye extracted from lichens, which are a symbiotic combination of fungi and algae. The most common lichen used for litmus extraction is Roccella tinctoria.

When it comes to scientific experiments and testing, litmus is a widely used indicator to determine the acidity or alkalinity of a substance. It changes color in response to the pH level of the solution it is placed in, making it a valuable tool for researchers and scientists.

Due to its versatility and reliability, litmus is used in various industries such as food and beverage, pharmaceuticals, and water treatment. It is also a popular choice for educational purposes in chemistry labs and classrooms.

Extracting litmus from lichens involves a careful process of harvesting, drying, and fermenting the lichen to release the natural dyes. The dye is then extracted and processed to create the iconic blue and red litmus paper strips that are familiar to many.

Using litmus paper is a simple and effective way to test the acidity or alkalinity of a substance. When dipped into a solution, the litmus paper will turn red if the solution is acidic and blue if it is alkaline. If the solution is neutral, the litmus paper will remain unchanged.

Overall, litmus is a valuable tool for determining the pH level of a substance and is derived from lichens, specifically Roccella tinctoria. Its ease of use and accuracy make it a staple in laboratories and industries around the world.

In conclusion, litmus is an essential indicator that plays a crucial role in various scientific fields and industries. Its extraction from lichens showcases the intricate processes involved in creating this valuable tool for pH testing.
