acid to produce water. The remaining sodium ion (Na+) and the polyatomic (CH3COO-) acetate ion form the soluble salt sodium acetate‚ NaCH3COO(aq)‚ which remains dissociated in solution. This acid-base reaction is called a neutralization reaction and has the general form: Acid + base a salt + water For the reaction of acetic acid with sodium hydroxide‚ the chemical equation is written as: HC2H3O2(aq) + NaOH(aq) -(H2O) Na+(aq) + C2H3O2-(aq) + H2O(l) The progress of a neutralization reaction
