In this lecture, we're going to look at something called salts. Now, salts are formed whenever acids and bases react. So for example, let's look at a hypothetical reaction of a hypothetical acid and a hypothetical base. So we have HX plus MLH. So these guys associate to form the H ion, xion, Emion and hydroxide ion. So this H plus ion and the hydroxide ion will react to form water and this Xion and the Mion will react to form our salt.
