The formula for boric acid is $H_3BO_3$ .........

Explanation:

And we could represent its ionization as......

$H_3BO_3 + H_2O rightleftharpoons H_2BO_3^(-) + H_2O$

$K_a=5.75xx10^(-10)$ ........and thus a second ionization would be unlikely. In fact, when we titrate boric acid, we often add excess mannitol, (a sugar), to bind to the acid, and this species gives a better endpoint.....
