The correct answer is option C.
Explanation:
The nomenclature of ionic compounds is given by:
1. Positive is written first.
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is ‘-ide’, ‘ate’ , ‘ite’ according to polyatomic anion.
The chemical formula for the compound ammonium phosphate:
Name of the cation = ammonium = [tex]NH_4^{+}[/tex]
Name of the anion = phosphate = [tex]PO_4^{3-}[/tex]
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the chemical formula for the given compound is
Ammonium phosphate = [tex](NH_4)_3PO_4[/tex]
[tex]What is the chemical formula for the compound ammonium phosphate? use the list of polyatomic ions a[/tex]
