Determining conjugate base of HCOOH

Postby Sophia Jin 3B » Tue Jan 23, 2024 10:58 pm

I know the CB for HCOOH is HCOO- because I've memorized that it is by now, and I get that the H is removed, but why is it HCOO- and not just HCOOH? Is it because the H carries a positive charge?

Yes, the H+ is lost which is the positive charge. HCOOH -> HCOO- + H+

Yes, H+ is the proton that is lost in HCOOH. Also, if you calculate the formal charge of HCOO-, you get a negative 1 charge on one of the oxygen atom.
