Question

what polyatomic ion is present in the following formula? kmno4 ammonia nitrate permanganese permanganate

Explanation:

• Ammonia (\(NH_3\)) is a neutral molecule, not a polyatomic ion.
• Nitrate is \(NO_3^-\).
• There is no polyatomic ion named permanganese.
• \(KMnO_4\) dissociates into \(K^+\) and \(MnO_4^-\). The \(MnO_4^-\) polyatomic ion is called permanganate.

Answer:

permanganate
