About This Product
This reagent is used to make up copper(II) chloride solutions for chemistry practicals and for analysis procedures that call for cupric chloride. Teachers use it when covering copper salts, chloride compounds, hydrate chemistry and transition-metal ions, and to show how hydrate-corrected weighing changes solution concentration. Handling calls for protection of eyes, skin and clothing. The Cupric Chloride Testing Reagent is available for supply within India and for export to Somalia, Bolivia, Jordan, Democratic Republic of the Congo and Croatia.
Frequently Asked Questions
Q1. What is the difference between anhydrous and dihydrate cupric chloride?
Anhydrous cupric chloride is CuCl2 at about 134.45 g/mol, while the dihydrate, CuCl2·2H2O, is 170.48 g/mol. The extra water changes the mass needed for a given concentration, so calculations use the form actually supplied.
