Product Code : SCL-LC-12178
The Red Litmus Solution pH Indicator is a laboratory indicator solution used to identify basic or alkaline samples by a red-to-blue colour change. It is suitable for supervised chemistry laboratories, schools, colleges, universities, STEM labs, distributors and procurement buyers requiring a simple acid-base teaching reagent.
Product Description
Red Litmus Solution from Science Lab Supplies is positioned as a chemistry-lab indicator for controlled educational and laboratory use. The supplied product name confirms red litmus solution, but bottle capacity, solvent base, indicator concentration, preservative, batch number, SDS and Certificate of Analysis must be verified before final catalogue publication.
Red litmus solution is used for qualitative acid-base testing. It remains red in acidic conditions and changes towards blue in alkaline conditions. It gives a fast visual result for teaching and screening, but it is not a substitute for a calibrated pH meter when exact pH values are required.
Key Features
- Clear teaching function: helps demonstrate the difference between acidic and basic solutions.
- Primary colour response: red litmus changes to blue in basic or alkaline samples.
- Ready-to-use solution: suitable for dropwise use in supervised laboratory tests [confirm].
- Bottle capacity to confirm: final pack size must be checked before publishing.
- Concentration to confirm: indicator strength and solvent base must be verified from the label or SDS.
- Student-friendly demonstration: useful for school chemistry activities under teacher supervision.
- SDS-led handling: use according to the current Safety Data Sheet and laboratory procedure.

How to Use the Red Litmus Solution
- Verify the label, bottle condition, batch number and expiry date before use.
- Place a small quantity of the test sample in a clean test tube or spotting tile.
- Add one or two drops of Red Litmus Solution using a clean dropper.
- Observe the colour change immediately under good light.
- Record the result: red-to-blue indicates a basic or alkaline sample.
- Use a pH meter or pH paper if a numerical pH value is required.
- Dispose of used samples according to the laboratory method and sample hazard.
Safety note: Do not taste, inhale or directly touch indicator solutions or tested samples. Wear eye protection and gloves where required. Treat unknown samples as laboratory chemicals until identified.
Care & Maintenance
- Store the bottle tightly closed in a cool, dry chemical-storage area.
- Keep away from direct sunlight, contamination and incompatible test samples.
- Do not return used solution to the original bottle.
- Discard if the solution is contaminated, faded, leaking, unlabelled or beyond verified shelf life.

Frequently Asked Questions
What is Red Litmus Solution pH Indicator used for?
Red Litmus Solution pH Indicator is used to detect basic or alkaline samples through a red-to-blue colour change in supervised chemistry laboratories.
Does red litmus solution test acids or bases?
Red litmus solution is mainly used to identify bases. It turns blue when the tested sample is basic or alkaline.
Can Red Litmus Solution give an exact pH value?
No. Red Litmus Solution gives a qualitative acid-base indication. Use a calibrated pH meter or suitable pH paper for numerical pH measurement.
What bottle capacity is available?
The bottle capacity is not confirmed. Add pack size only after checking the final product label or catalogue specification.
Is Red Litmus Solution safe for schools?
Yes, it is suitable for supervised school chemistry laboratories when used with standard lab safety practices and the current SDS.
How should Red Litmus Solution be stored?
Store it tightly closed, away from direct sunlight and contamination, according to the verified label and SDS instructions.
