## Description

Litmus paper doesn't have a precise numerical scale; instead, it shows a color change to indicate acidity or alkalinity. Red litmus paper turns blue in a basic (alkaline) solution, and blue litmus paper turns red in an acidic solution. A solution is neutral if the litmus paper color does not change. The colors are interpreted against the standard pH scale, where values below 7 are acidic, 7 is neutral, and values above 7 are alkaline. How the Litmus Test Works 1. Acidic Test: Dip a piece of red litmus paper into the solution. If it remains red, the solution is acidic or neutral. Dip a piece of blue litmus paper. If it turns red, the solution is acidic. 2. Basic Test: Dip a piece of blue litmus paper into the solution. If it remains blue, the solution is basic or neutral. Dip a piece of red litmus paper. If it turns blue, the solution is basic (alkaline). 3. Neutral Test: If neither red nor blue litmus paper changes color, the solution is neutral. Interpreting the Results Acidic Solution: Causes red litmus paper to turn blue. Basic Solution: Causes blue litmus paper to turn red. Neutral Solution: Causes no color change in either red or blue litmus paper. Litmus Paper Limitations Litmus paper has a limited pH range, generally between 4.5 and 8.5. It only provides a qualitative (acidic/basic/neutral) indication, not a specific numerical pH value like a universal indicator or pH meter can litmus paper strips 100 blue strips and 100 red strips, acid base indicator strips for testing acid and base solutions,fun and learn activity for school,home and education institute experiment
