What is the chemical formula of Aluminium Nitrate?
Aluminum nitrate has a chemical formula of Al(NO3)3.
Let us see how one can reach this chemical formula given only the name of the compound. Aluminum is an element and has a chemical symbol of Al. It has a common oxidation state of +3 and is a metal. The oxidation state shows the number of electrons it has lost. Nitrate, on the other hand, is an anion and has an oxidation state of -1. Since the aluminum ion is formed by donating 3 electrons and nitrate requires only 1 electron, 3 nitrate ions react with each aluminum ion and this results in a chemical formula of Al(NO3)3.
Aluminum nitrate is a strong oxidizing agent and can be prepared by the reaction between nitric acid and aluminum chloride.
Hope this helps.
