Red Litmus pH Indicator Solution Manufacturer,Supplier and Exporter in India

Product Code : SCL-CA-12622

The Red Litmus pH Indicator Solution is an acid-base indicator solution used for checking alkaline behaviour, demonstrating pH change, and supporting supervised chemistry practicals. It is suitable for science teachers, laboratory technicians, school laboratories, college laboratories, STEM classrooms, distributors, and institutional procurement buyers.

Product Description

Red Litmus pH Indicator Solution from School Equipments India is prepared for the laboratory chemicals, pH indicators, and chemical-analysis reagent category. A direct verified product page for this exact indicator solution was not found, so pack size, concentration, solvent system, shelf life, bottle type, SDS, and COA should be confirmed before publication or purchase.

Litmus is a traditional acid-base indicator. In classroom use, red litmus remains red in acidic conditions and changes toward blue in alkaline conditions. It is useful for quick qualitative testing, but it does not provide a precise numerical pH value like a calibrated pH meter or full-range universal indicator.

Key Features

• Acid-base indicator solution: used to demonstrate whether a sample behaves as acidic, neutral, or alkaline.
• Alkalinity check: red litmus changes blue when exposed to a basic or alkaline solution.
• Classroom-ready reagent: suitable for supervised school and college chemistry demonstrations.
• Qualitative pH indication: shows acid-base behaviour without claiming exact pH measurement.
• Simple visual response: helps students observe colour change during pH-related experiments.
• Chemical-analysis category fit: useful in basic chemistry, solution testing, and materials-property lessons.
• Procurement-safe listing: unknown concentration, volume, solvent, and documentation are marked for confirmation.

Technical Specifications

What's Included in the Kit

• Dropper, test tubes, spot plate, pH chart, worksheets, and sample chemicals are not included unless confirmed in the final quotation.

Applications / Uses

• Testing whether a solution shows alkaline behaviour
• Demonstrating colour change in acid-base chemistry practicals
• Supporting school lessons on acids, bases, neutralisation, and pH indicators
• Checking prepared classroom samples during teacher-led demonstrations
• Comparing litmus response with universal indicator or pH meter readings
• Supporting institutional procurement of chemistry-lab indicator reagents

How to Use the Red Litmus pH Indicator Solution

1. Read the product label, SDS, and laboratory risk assessment before use.
2. Pour a small quantity of the test sample into a clean test tube or spot plate well.
3. Add one or two drops of Red Litmus pH Indicator Solution to the sample.
4. Observe the colour change against a white background for clearer visibility.
5. Record whether the solution remains red or changes toward blue.
6. Use fresh glassware for each sample to avoid cross-contamination.
7. Do not return used indicator or mixed solution to the original bottle.
8. Dispose of tested mixtures according to the sample chemical and laboratory SOP.

Safety note: Treat all tested samples as laboratory chemicals. Wear eye protection and gloves, avoid ingestion or skin contact, and supervise students during indicator experiments.

Care & Maintenance

• Store tightly closed in a labelled reagent-storage area.
• Keep away from heat, strong light, contamination, food items, and unauthorised users.
• Use clean droppers or dispensing tools to prevent dilution and contamination.
• Replace faded, contaminated, unlabelled, or expired solution according to laboratory procedures.

Frequently Asked Questions

What is Red Litmus pH Indicator Solution used for?

Red Litmus pH Indicator Solution is used to check whether a solution is alkaline and to demonstrate acid-base indicator colour change in supervised chemistry practicals.

What colour does red litmus turn in a base?

Red litmus turns blue in a basic or alkaline solution. This makes it useful for quick qualitative alkalinity checks.

Does red litmus give an exact pH value?

No. Red litmus is a qualitative acid-base indicator. Use a pH meter or suitable universal indicator system when a numerical pH value is required.

What is the pH range of litmus?

Litmus references commonly list a colour-change range around pH 5.0-8.0. The exact performance of a supplied solution should be confirmed from its datasheet.

Can it be used in school laboratories?

Yes. It is suitable for supervised school and college chemistry laboratories when teachers control sample handling, PPE, labelling, disposal, and contamination prevention.

What documents should be confirmed before ordering?

Confirm the SDS, concentration, pack size, batch number, expiry or retest date, label details, and final packaging before ordering.
