Well, let's see. Now let's look at the reaction of sodium hydroxide with hydrochloric acid. Initially, we only have HCL in our mixture and HCL dissociates into H plus ion and the chloride ion. Now, the H plus ion is what's responsible for creating the acidic solution for lowering our PH to a PH of two. So what will happen when we first dissociate or add NaOH to our mixture? Well, initially we only have a small amount of NaOH, and NaOH will dissociate into Ma plus and oh minus.
