Discusses chemical reactions that occur when acids and bases interact. The reactions are just the same as with acids like hydrochloric acid, except they tend to be rather slower. Finally, we cross out any spectator ions. The purpose of ionic equations is they simplify chemical equations by eliminating the species that arent undergoing any change. Since the acid and base are both strong, they are fully ionized and so are written as ions, as is the \(\ce{NaCl}\) formed as a product. Ions that do not take part in the reaction are referred to as spectator ions. GCSE Physics. 5.5: Neutralization Reactions - Chemistry LibreTexts In a molecular equation, all the species are represented as molecules, even the compounds that exist only as ions in the solution. In the process, a lot of wastewater with an alkaline pH is generated. In other words, the ions that react together in solution and form new substances.
