"Formula of Nickel (II) Acetate"

There is now a formula for nickel (II) acetate. Nickel, a chemical element, has a divalent valence state. Acetate is a common group in chemistry.

To obtain the formula of nickel (II) acetate, it is necessary to know that nickel (II) ions have two units of positive charge, expressed as $Ni ^ {2 +} $; acetate ions, the symbol is $CH_ {3} COO ^{ - }$， have one unit of negative charge.

According to the reason that the sum of positive and negative charge algebras in the compound is zero, in order to balance the charge, one nickel (II) ion needs to be combined with diacetate ion.

Therefore, the chemical formula of nickel (II) acetate is $Ni (CH_ {3} COO) _ {2} $. This formula is established and is an important basis for chemical research and experiments.
