Interpretation:
The given set of molecular equations has to be completed and net ionic equation has to be found.
Concept introduction:
Neutralization Reaction: In neutralization reactions acid and base reacts together to form water and an ionic compound(salt).
A chemical equation is the figurative representation of chemical reaction. In a chemical equation the reactants are in the left side and the products are in the right side. A balanced chemical equation serves as an easy tool for understanding a chemical reaction. There are mainly three types of chemical equations, molecular equations, complete ionic equation and net ionic equation.
In molecular equations the reactants and products are represented as molecular substances, even though they exist as ions in solution phase. The molecular equation for the reaction between
This equation is helpful in understanding the reactants and products involved in the reaction.
In complete ionic equations the electrolytes are represented as its ions. Soluble compounds exist as ions in solution. Complete ionic equation is helpful in understanding the reaction at ionic level. The complete ionic equation for the reaction between
