Litmus Paper, Blue, Pack of 100
Product Code: LITPAPB
Blue Litmus paper was used to determine whether or not a solution is acidic. Litmus paper is an outdated indicator for acids and bases. It is now substituted with more advanced indicators cuch as Universal pH papers that can identify acids and bases while measuring their strengths.
Today some students use red cabage juice to make their own litmus paper for educational purpose. But litmus paper has no other application and universal pH papers are used instead.
