Okay let's say we have water, sodium hydroxide and hydrogen chloride. What do you think is going to happen? Do you think the pH will be the same, a little higher, or a little lower? You have this reaction down here: H2O+NaOH+HCl(assuming they are equal)= H2O+OH-+Na+(positive charge)+H+(positive charge)+Cl-=H2O+NaCL Let me explain what happens. The sodium hydroxide dissasociates completly into Na+ and OH-. The hydrogen chloride dissasociates completly into H+ and Cl-. The H+ and OH- are attracted and form a water molecule. The Na+ and Cl- are attracted and form NaCL or table salt. this table salt formation makes the water have a pH of 8 intead of 7 meaning that when you start off with a neutral, strong base, and strong acid in equal amounts you get a weak base as the result. Somebody else said that it will be neutral but I have looked up the pH of saltwater(which is what is forming in this reaction) and it is 8 not 7.
