So a strong acid, hydrochloric acid and a strong base, sodium hydroxide dissociate to form an H plus ion, a chloride ion, sodium ion and hydroxide ion. Now, in the same way that these guys react to form water, these two guys will react to form our water, while these two guys will react to former salt. Now, notice I wrote mutual salt. And in fact, strong acids and strong bases react to form Mutual Salt. And that's because our Final Solution has no presence of acids or bases. And let's see why.
