The molecular formula for nickel carbonate is NiCO3.
The chemical formula for nickel(II) chloride is NiCl2.
The chemical formula for nickel chloride dihydrate is NiCl2•2H2O. This formula indicates that each formula unit of nickel chloride dihydrate contains one nickel atom, two chloride ions, and two water molecules.
The formula name of Ni2(CO3)2 is nickel(II) carbonate.
The chemical formula for Nickel Chloride Hexahydrate is NiCl2•6H2O.
Prepare a solution of a nickel salt such as sulfate, nitrate, chloride, etc. This can be done by dissolving pieces of nickel in a strong acid mixture. Once you have the nickel salt, neutralize the solution and add excess baking soda. Then filter out the fine light green nickel carbonate.
Nickel (II) oxalate dihydrate; used in battery production.
NiCO3
The chemical formula of nickel chloride hexahydrate is NiCl2·6H2O. It consists of one nickel ion (Ni^2+), two chloride ions (Cl^-), and six water molecules (H2O).
(Ni)2CaCO3
Nickel carbonate reacts with dilute hydrochloric acid to produce nickel chloride, carbon dioxide gas, and water.
