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