About This Product
Nickel sulphate solutions are prepared for practicals on transition-metal salts and for controlled demonstrations of electrochemistry and plating principles. The supplied form, anhydrous or hydrated, is identified on the label before weighing. Splash goggles, gloves and a lab coat are worn, dust and skin contact are avoided, and clean, dry tools are used to take only the quantity required. The Nickel Sulphate Reagent is available for supply within India and for export to Sierra Leone, Slovenia, Syria, Rwanda, Uruguay and Uzbekistan.
Frequently Asked Questions
Q1. Which nickel sulphate forms are there? The anhydrous salt is NiSO4, and common hydrated forms include the hexahydrate NiSO4·6H2O and the heptahydrate NiSO4·7H2O, each with a different molecular weight and colour.
