<p>I'm reviewing for a test on acids and bases, and there is a difference in my books.
In my textbook, it says the equation for Ka= [H30+][Base]/[Acid]
it also says when finding pH, you do -log[H30+]
it constantly says hydronium ions throughout the chapter</p>

<p>while my PR AP chem book says the equation for Ka= [H+][B-]/[HB]
and pH=-log[H+]</p>

<p>so why does one use Hydrogen ions for everything, while the other uses hydronium?</p>

<p>The concentrations of hydronium ions and the concentration of hydrogen ions is basically the same. I think they're just different ways of expressing the same thing.</p>

<p>They're the same thing. The more correct way of writing it is "H3O+", but they're the exact same thing.</p>
