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. But since we only have a small amount of NaOH, that means we only have a small amount of these guys. And these guys are the ones that associate with HMCL to form water and NaCl. So initially, only a small percentage of these guys will reassociate into this form.
