Upper N upper H subscript 4 superscript plus. and Upper S upper O subscript 4 superscript 2 minus.
Explanation:
The spectator ions in this reaction are the ammonium ion and the sulfate ions.
In a reaction, not all of the ions are reacting. The ions not reacting are called the spectator ions.
When we eliminate such ions, we get an overall view of the reaction.
The reaction is:
2NH₄⁺ + 2OH⁻ + 2H⁺ + SO₄²⁻ ⇒ 2NH₄⁺ + 2H₂O + SO₄²⁻
In ionic equations, water soluble reactants and products are split into their constituent ions while non-ionizing or gaseous reactants and products are represented as formulae or molecules.
The species that are not reacting and appears on both sides are 2NH₄⁺ and SO₄²⁻ and are the spectator ions.
These non-reactive species are eliminated from the overall ionic equation that shows the reacting ions only.
