Answer:
In conclusion, the net ionic equation for the reaction between calcium carbonate and hydrochloric acid is CaCO3 solid plus two H+ aqueous react to form Ca2+ aqueous plus CO2 gas plus H2O liquid.
When calcium carbonate reacts with hydrochloric acid, calcium ions are transferred to the solution, the the net ionic equation is CaCO₃(s) + 2H⁺ → Ca²⁺ + CO₂ + OH⁻ + H⁺.
Net ionic equation of any reaction is the equation where all entities are written in the form of ions except spectator ions.
Given chemical reaction is:
CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + CO₂(g) + H₂O(l)
Ionic reaction for the above reaction will be written as:
CaCO₃(s) + 2H⁺ + 2Cl⁻ → Ca²⁺ + 2Cl⁻ + CO₂ + H⁺ + OH⁻
In the baove reaction Cl⁻ is the spectator ion as they are present on both sides of the given chemical reaction. So the net ionic reaction will be written as:
CaCO₃(s) + 2H⁺ → Ca²⁺ + CO₂ + OH⁻ + H⁺
Hence the net ionic reaction is CaCO₃(s) + 2H⁺ → Ca²⁺ + CO₂ + OH⁻ + H⁺.
