(see spectator (a) Put a cross in the box to indicate your answer. This is the reaction that always occurs when an acid + alkali salt + water. Reactions between acids and bases that are both weak may result in solutions that are neutral, acidic, or basic. The sodium and chloride ions are spectator ions in the reaction, leaving the following as the net ionic reaction. a reaction in which an acid and a base react in an aqueous solution to produce a salt and water with a neutral pH (pH = 7). A salt is essentially any ionic compound that is neither an acid nor a base. Redox reactions are therefore two-part reactions, and its possible to split the overall chemical equation representing a redox reaction into two chemical equations, one of the reduction, one for the oxidation.
