The net ionic equation for the acid-base reaction of hydrochloric acid with phosphine is PH3(aq) + H⁺(aq) → PH⁺₄ (aq)
A chemical reaction shows us how substances interact which brings about changes in the composition of the reactants. Two types of Chemical reactions includes:
The net ionic equation of a chemical equation tells us only elements and ions directly involved in the chemical reaction.
Now for the reaction of hydrochloric acid, HCl with phosphine, PH3,
First write the aqueous substances in their ionic components
PH3(aq) + HCl(aq)→ PH4Cl(aq)
PH3(aq) + H⁺(aq) +Cl⁻(aq) → PH⁺₄ (aq) + Cl⁻(aq)
Then we remove the ions that do not take part in the reaction, Cl⁻(aq)
So we are left with
PH₃(aq) + H⁺(aq) → PH⁺₄ (aq)
Therefore, the net ionic equation for the reaction of hydrochloric acid with phosphine is PH₃(aq) + H⁺(aq) → PH⁺₄ (aq)
