What Is Litmus Paper Used For?
Litmus is a dye obtained from lichens, and paper soaked in it is the simplest acid–base indicator in a school lab. Acids turn blue litmus red, alkalis turn red litmus blue, and a neutral solution changes neither colour, so using both papers tells all three apart. It is the indicator students meet in the acids, bases and salts lessons of class 7 and class 10 science, and an everyday check in college chemistry and biology labs, for example to confirm that a solution has been neutralised. Moistened with distilled water, it also tests gases: ammonia turns damp red litmus blue, and chlorine bleaches damp litmus.
Litmus only shows whether a solution is acidic or alkaline — it does not give a pH value, for which universal pH paper or a pH meter is used. For clean results, touch a drop of the test liquid onto a strip with a glass rod, on a spot plate or white tile, instead of dipping strips into stock bottles. Keep the box closed and dry and store it away from acid and ammonia fumes, which can change the colour of unused leaves.
What to Specify When Ordering
- Colour — red, blue, or a quantity of each; most practicals use both.
- Quality — regular for schools, or extra superior for colleges and universities.
- Quantity — the minimum order is 10 boxes; plan by the number of benches and practical sessions.
- Related indicators — add universal pH paper or litmus solution if the same course needs them.
Frequently Asked Questions
How does litmus paper show an acid or an alkali?
By changing colour. An acid turns blue litmus paper red and an alkali turns red litmus paper blue; a neutral liquid leaves both colours unchanged.
What does one box contain?
5 books with 20 leaves each, so 100 leaves, packed in a plastic box. Each leaf measures about 63.5 x 10 mm.
Do I need both red and blue litmus paper?
For a complete test, yes. With only one colour you can confirm one type of substance, but you cannot tell the other type from a neutral one; red and blue together separate acid, alkali and neutral.
Can litmus paper give a pH value?
No. It shows only whether a solution is acidic or alkaline. Use universal pH paper with its colour key, or a pH meter, when you need a number.
What is the difference between the regular and extra superior quality?
The regular quality is listed for schools and simple testing, and the extra superior quality for colleges and universities. Tell JLab where the paper will be used and it will quote the matching grade.
What is the shelf life of litmus paper?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keeping the box sealed, dry and away from fumes helps the leaves keep their colour.
Who manufactures this litmus paper?
Jain Laboratory Instruments Pvt Ltd (JLab) produces it at its works in Ambala, Haryana, India, and supplies it under the JLab brand as the manufacturer.
