Litmus Paper Blue Manufacturer,Supplier and Exporter in India

Litmus Paper Blue (Product Code: SCI-575/147) is an acid-detecting indicator paper used to test whether a solution or damp gas is acidic in school and college laboratories. Acids turn the blue paper red, while bases and neutral substances leave it blue, so a single piece gives a quick yes-or-no answer on acidity. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which provides litmus paper to schools across India and abroad.

Key Details

What Is Blue Litmus Paper Used For?

Touch a piece with a glass rod dipped in the test liquid: a red colour means the sample is acidic. Because bases and neutral liquids both leave blue litmus unchanged, pair it with red litmus paper — if the red paper turns blue the sample is basic, and if neither changes it is neutral.

Moistened with distilled water, blue litmus paper also identifies acidic gases such as hydrogen chloride and sulfur dioxide at the mouth of a test tube, while chlorine first reddens it and then bleaches it. Handle the paper with dry fingers or forceps and keep the pack closed away from acid fumes, which slowly redden it; this simple habit keeps acid-base indicator practicals reliable.

Frequently Asked Questions

What colour does Litmus Paper Blue turn in acid?
Litmus Paper Blue turns red in acids. In bases and in neutral substances it stays blue, so the blue paper is the one to use when the question is whether a sample is acidic.

Can Litmus Paper Blue tell a base from a neutral solution?
No. Litmus Paper Blue stays blue with both bases and neutral substances. To separate them, also test with red litmus paper, which turns blue only in a base; no change on either paper means the sample is neutral.

How is Litmus Paper Blue used to test gases?
Moisten Litmus Paper Blue with distilled water and hold it at the mouth of the test tube without touching the glass. An acidic gas such as hydrogen chloride turns the damp paper red; dry paper does not respond reliably.

How should Litmus Paper Blue be stored?
Store Litmus Paper Blue in its closed pack in a dry place away from acid fumes, which can turn it red before use. Shelf life depends on storage conditions; ask us for the expiry date of the batch you are quoted.
