StemAids pH Paper, Wide Range is an educational laboratory testing paper designed for quick estimation of the acidity or alkalinity of aqueous solutions. It is suitable for school chemistry laboratories, college science labs, biology practicals, environmental science activities, water testing demonstrations, STEM classrooms, and teacher-supervised practical sessions.
Wide range pH paper helps students identify whether a solution is acidic, neutral, or alkaline by comparing the colour change on the test strip with the supplied pH colour chart. It is a simple and practical tool for introducing pH scale, acids, bases, indicators, neutralisation, water quality testing, and basic chemical analysis.
Product Highlights
- Wide range pH paper for quick acidity and alkalinity testing
- Useful for chemistry, biology, environmental science, and STEM practicals
- Helps identify acidic, neutral, and alkaline solutions
- Easy colour comparison method using pH reference chart
- Suitable for school, college, laboratory, and classroom demonstrations
- Recommended for teacher-supervised educational laboratory use
Product Description
The StemAids pH Paper, Wide Range is designed to provide a simple visual method for estimating the pH value of suitable liquid samples. When the pH paper comes in contact with a solution, the indicator dyes on the paper change colour according to the acidity or alkalinity of the sample.
Students can compare the resulting colour with the pH chart to estimate the pH level. This makes it useful for testing classroom-safe samples such as water, diluted acid or alkali solutions, soil water extracts, laboratory solutions, and selected environmental samples under teacher guidance.
StemAids provides educational science products that support hands-on learning, practical observation, and safe classroom demonstrations. StemAids pH Paper, Wide Range is suitable for chemistry labs, biology labs, environmental science projects, STEM activities, and institutional procurement.
