About This Product
One or two drops are added to a small sample in a clean test tube or spotting tile, and students note the colour change against their practical guide. Fresh samples are used for each test to avoid cross-contamination. The indicator gives a qualitative result, so it serves for teaching and for comparison with red litmus, universal indicator or pH paper rather than for exact pH values. The Blue Litmus Laboratory Standard is available for supply within India and for export to United Kingdom, Armenia, Tunisia, Gabon and Mali.
Frequently Asked Questions
Q1. Can blue litmus solution give an exact pH value?
No. It shows qualitative acid-base behaviour. For exact pH values a calibrated pH meter or a suitable universal indicator method is used.
