I was wondering on how to get an acid and a base. When metal reacts with water does it create a baser or a base solution. What about acids? If a nonmetal reacts with water does it create an acid or an acid solution?
What will be the pH at the equivalence point when a 100 mL sample of 0.25 M NH3 titrated with 0.15 M HCl at 25 degrees C? (Kb for NH3 = 1.8 x 10-5)
