To balance NaOH + HCl = NaCl + H2O you'll need to be sure to count all of atoms on each side of the chemical equation. The substances entering into the reaction are in an identical physical state – an identical liquid state. The reaction is not an oxidation-reduction reaction: the oxidation states of the atoms did not change over the course of the reaction. Sodium chloride is made up of Na + cations from the base (NaOH) and Cl − anions from the acid (HCl). Even “Romeo and Juliet” has a happy ending there. Hydrochloric acid, #"HCl"#, is a strong acid that ionizes completely in aqueous solution to produce hydrogen cations and chloride anions #"HCl"_ ((aq)) -> "H"_ ((aq))^(+) + "Cl"_ ((aq))^(-)# Sodium hydroxide is a strong base when dissolved in water, which implies that it too ionizes completely to produce sodium cations and hydroxide anions..
