sorry to keep blowing up this forum but i just need to clarify things before my test

from GS-9

wouldn't the CONJUGATE ACID be H30+ and the CONJUGATE BASE be HC03-. The ACID would be H2CO3 and the BASE would be H20.

For a conjugate acid-base pair, the acid acts as a bronsted acid (donating a H+). What's left after it donates an H+ is it's conjugate base (HCO3-). You could also view it the opposite way. If HCO3- acts as a base (abstracts a proton), it's conjugate acid is H2CO3.

Also, in your explanation, water is acting as a base (it's accepting the proton of H2CO3). So water's conjugate acid is H3O+.

woops just noticed i didn't post the passage the question was referring to. could you take a look at it again?
