A net ionic equation is a chemical equation that shows only the species that are involved in a chemical reaction. It excludes spectator ions, which are ions that do not participate in the reaction and remain unchanged.
To write a net ionic equation, first write the balanced molecular equation for the reaction. Then, identify the spectator ions and cross them out. Finally, rewrite the remaining species as the net ionic equation.
The purpose of writing a net ionic equation is to simplify the representation of a chemical reaction and focus on the species that are actually involved in the reaction. This can help in understanding the main chemical process taking place.
No, a net ionic equation cannot be used to predict the products of a reaction. It only shows the species involved in a reaction, not the actual products that will be formed.
No, a net ionic equation can only be used for reactions that take place in aqueous solutions. It is not applicable to reactions that occur in the gas or solid phase.
