None of these answers is really correct, a better answer would be: f]ANY of the above. The question asked [or the information given] is incomplete, or erroneous. Is a strong [or a weak] acid reacting with a strong or a weak] base? What is the nature of the salt that is formed? Will it hydrolyse? I assume that when the acid reacts with the base in "equal proportions", this means that one mole [or equivalent] of acid with one mole [or equivalent] of base, that one mole or formula weight, or equivalent weight of salt is formed, with no acid or base left over. One mole [or eq.wt.] of HCl reacts with one mole [or eq.wt.] of NaOH, to form one mole of NaCl. The solution will be nearly neutral,i.e. pH =7. 1 mole NaOH and 1 mole of Acetic acid, Sodium acetate is formed. A 0.1 Molar solution of sodium acetate has a pH = 8.9 Ammonium Hydroxide and NaOH, same conditions. Ammonium Chloride is formed, and a 1 Molar solution of this a pH of about 5. Maybe one of the "Super Acids' would react with a very weak base yield a pH of O, but I cant think of a good example. Conversely, for pH=14. The equations for the pH of a salt are given in any chemistry text or the CRC or LANGE'S handbooks. Regards Charlie Crutchfield
