Consider the total ionic equation below.

ba2++2no3-+2na++co2/3- > > > > > > baco3 +2na++2no3-

which is the net ionic equation for the reaction?

Answer;

Ba²⁺(aq) + CO₃²⁻(aq) → BaCO₃(s)

Explanation;

Ionic equation is a chemical equation that is written only showing the ions that have changed state in the course of a reaction. The rest ions called spectator ions are not involved in the reaction and do not change state thus they are not included when writing ionic equations.

-Aqueous compounds ionize in water to form corresponding ions, while precipitates, gases and pure liquids do not.

In our case; The only ions involved are Ba²⁺ and Co3²⁻, the rest are spectator ions, that is, NO3⁻ and Na⁺.

Thus the ionic equation will be;

Ba²⁺(aq) + CO₃²⁻(aq) → BaCO₃(s)

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
