About This Product
Chromium sulphate is used to prepare chromium(III) sulphate solutions for chemistry practicals and in analysis procedures that specify this salt. It also supports teaching on transition-metal salts, sulphate compounds and hydrate calculations. Since hydrated material carries a variable amount of water, the hydrate level on the label sets the molecular weight used for weighing. It is meant for trained teachers and laboratory technicians working with suitable protective equipment. The Laboratory Reagent Chromium Sulphate is available for supply within India and for export to São Tomé and Príncipe, Laos, United Kingdom, Vanuatu, Grenada and Colombia.
Frequently Asked Questions
Q1. Why does the hydrate form of chromium sulphate matter?
Hydrated chromium sulphate, Cr2(SO4)3·xH2O, holds a variable amount of water. That changes its molecular weight, so the hydrate level affects weighing calculations and the strength of any solution prepared from it.
