It places an important role in crop plants. It is used to make fertilizers, nitric acid, dies explosives, and nylon. Nitrogen is found in soils and plant cells. It is so vital because it is a major component of Proteins.
Cobalt (II) Nitrate
Cobalt (II) Nitrate is an inorganic compound. It is a cobalt salt in which the cobalt metal is the +2 oxidation state and the counter anion is nitrate. It is an odorless red solid chemical that sinks and mixes with water. It is used in the preparation of dyes and inks. This substance is possibly carcinogenic to humans.
To write the formula for Cobalt (II) Nitrate first we need to write the element symbols. Cobalt is the chemical element with the symbol Co. In this compound, cobalt has a +2 charge of Co2+. And nitrate has a negative charge NO3–. We need to balance the charges for this to follow the Criss-Cross method to make the net charge zero. Finally, the chemical formula for Cobalt (II) Nitrate is Co(NO3)2
Structure Of Cobalt (II) Nitrate
The chemical formula of Cobalt (II) Nitrate is Co(NO3)2. In this cobalt is metal and nitrogen and oxygen are nonmetals. Metal and nonmetals are grouped together to form ionic compounds. Valance electrons are transferred to non-Cobalt (II) means Co has +2 charge Co2+. Nitrate has a negative charge of NO3–. Cobalt lost electrons to nitrate ions because nitrate has a negative charge. Cobalt (II) Nitrate is normally a crystal. The Lewis structure for Cobalt (II) Nitrate is as follows.
