Final answer:
The net ionic equation for the reaction between barium chloride and calcium nitrate shows no reaction occurs, as all of the products are soluble in water and no precipitate is formed.
Step-by-step explanation:
Net Ionic Equation for Reaction Between Barium Chloride and Calcium Nitrate
The reaction between barium chloride and calcium nitrate can be represented by the following overall chemical equation:
BaCl2(aq) + Ca(NO3)2(aq) → Ba(NO3)2(aq) + CaCl2(aq)
Both barium nitrate (Ba(NO3)2) and calcium chloride (CaCl2) are soluble in water and will dissociate into their respective ions. Therefore, in the complete ionic equation, all ions are shown as being separate in the solution:
Ba2+(aq) + 2Cl−(aq) + Ca2+(aq) + 2NO3−(aq) → Ba2+(aq) + 2NO3−(aq) + Ca2+(aq) + 2Cl−(aq)
Since all ions remain in solution and no precipitate is formed, each ion appears on both sides of the equation. This indicates that there is no change in the physical state of these ions and they are all spectator ions. Thus, when writing the net ionic equation, all of these ions will cancel out as they do not participate in the reaction:
Net ionic equation: No reaction occurs.
In this case, because all of the products are soluble and no precipitation, gas release, or electron transfer occurs, there is no actual chemical reaction occurring. Hence, it's accurate to state that there is no net ionic equation for the mixing of barium chloride and calcium nitrate in aqueous solution since no reaction takes place.
