(compare this reaction with the ionisation of water). Reactions between acids and bases that are both weak may result in solutions that are neutral, acidic, or basic. The interesting thing (and useful fact for revision purposes) is that all neutralisation reactions have this same ionic equation. The full ionic equation for the neutralization of hydrochloric acid by sodium hydroxide is written as follows: Since the acid and base are both strong, they are fully ionized and so are written as ions, as is the NaCl formed as a product.
