The nature of this equilibrium situation, as you recall from General Chemistry, is expressed by an equilibrium constant, K eq. Rather, a dynamic equilibrium is reached, with proton transfer going in both directions (thus the two-way arrows) and finite concentrations of all four species in play. Notice the phrase вЂto some extentвЂ™ вЂ“ this reaction does not run to completion, with all of the acetic acid converted to acetate, its conjugate base. When a small amount of acetic acid is added to water, a proton-transfer event (acid-base reaction) occurs to some extent. We will consider acetic acid as our first example. The common base chosen for comparison is water. The relative acidity of different compounds or functional groups вЂ“ in other words, their relative capacity to donate a proton to a common base under identical conditions вЂ“ is quantified by a number called the dissociation constant, abbreviated K a. Even hydroxide ion could theoretically act as an acid вЂ“ it has, after all, a proton to donate вЂ“ but this is not a reaction that we would normally consider to be relevant in anything but the most extreme conditions. Water, which we know can act as a proton donor, is obviously not a very strong acid.

Acetic acid (vinegar), will also burn your skin and eyes, but is not nearly strong enough to make an effective drain cleaner. Not surprisingly, concentrated sulfuric acid will also cause painful burns if it touches your skin, and permanent damage if it gets in your eyes (thereвЂ™s a good reason for those safety goggles you wear in chemistry lab!). Sulfuric acid is strong enough to be used as a drain cleaner, as it will rapidly dissolve clogs of hair and other organic material. You are no doubt aware that some acids are stronger than others.
