About This Product
A small strip is removed with clean, dry hands or forceps and touched with a drop of the solution. If it turns blue, the solution is alkaline. Comparing the result with blue litmus paper helps students see how the two papers work together in lessons on acids, bases, indicators and neutralisation. Besides buyers across India, the Red Litmus Indicator Paper can be exported to institutions in Turkmenistan, Indonesia, Tajikistan, Republic of the Congo, Morocco and Palestine.
