Interpretation:
The number of ions present per formula unit in the following polyatomic ion containing compound -
Concept Introduction:
Chemical formulas and names for ionic compounds containing polyatomic ions:
Ionic compounds containing positive and negative charges present must add to zero.
If more than one polyatomic ion is present in a compound, the chemical formula can be written as a polyatomic ion is enclose in parentheses and a subscript, placed outside of the parentheses. Example-
Sometimes same element is present in two different locations. For example,
