About This Product
Benzoic acid is used in supervised purification exercises: students recrystallise it and then check the result by melting-point determination. It also illustrates weak-acid behaviour, solubility and the structure of aromatic acids. The solid is weighed with a clean, dry spatula while avoiding dust, and kept away from strong oxidants, strong bases and ignition sources. Besides buyers across India, the Benzoic Acid Testing Reagent can be exported to institutions in North Macedonia, Uruguay, São Tomé and Príncipe, United Arab Emirates and Iceland.
Frequently Asked Questions
Q1. Why is benzoic acid used in recrystallisation practice? It is a solid organic acid used in supervised purification and melting-point exercises, so students can purify a sample and then check its melting point.
