In solution, chemical species as simple as H+ and OH-canserve as catalysts for reactions. Imagine you couldmeasure the [H+] of a solution containing an acidcatalyzedreaction as it occurs. Assume the reactants andproducts themselves are neither acids nor bases. Sketchthe [H+] concentration profile you would measure as afunction of time for the reaction, assuming t = 0 is whenyou add a drop of acid to the reaction.
