The number of NH₄⁺ NH₄⁺ and CO₃⁻² CO₃⁻² ions required to form a neutral ionic compound are 2 and 1 respectively.
A Neutral Ionic Compound means a compound that is made by both positively and negatively charged ions i.e. cations and anions respectively.
NH₄⁺ is called as Ammonium ion formed due to addition of H+ (Proton) in Ammonia and CO₃⁻² is called as Carbonate ion formed with a Trigonal Planar structure.
For a compound having NH₄⁺ and CO₃⁻², a neutral compound can be made by keeping the total charge on the compound to be zero.
Hence, Ammonium carbonate (NH₄) ₂CO₃ is a neutral compound formed by taking 2 NH₄⁺ and 1 CO₃⁻² ions.
So, for the formation of the Neutral compound i.e. Ammonium carbonate (NH₄) ₂CO₃ , 2 NH₄⁺ and 1 CO₃⁻² is needed.
