Experiment 22
... Although the product, [H+] [OH-] is small, that does not mean that both concentrations are necessarily small. If, for example, we dissolve HCl in water, the HCl in the solution will dissociate completely to H+ and Cl- ions; in 1 M HCl, [H+] will become 1 M, and there is nothing that Reaction 3 can ...

... but you’ve yet to put numbers into the idea. So why do chemists use maths? Mostly, because it’s good for describing patterns clearly and because it allows chemists to put a number on things: rather than saying something increases we’d like to be able to say by how much. This might mean that you find ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
