I am a bit confused about writing the formulas of conjugate bases, in terms of what happens to hydrogen. In part d) we are given HCO3-, but then when we write the conjugate the hydrogen disappears. Is it because it is being added to the other side, causing the charge to change to 2-?

Also, in part f) CH3COOH, does the O2 in the answer represent the two O at. the end of the compound after hydrogen is removed? I hope my question makes sense lol

can someone explain the conjugate base.. is it just another way of saying weak? serious question

I am confused about part b. It is asking for the conjugate acid of NH2NH2. Both nitrogens have a lone pair, so could the hydrogen from H2O attach to either one?

Yes, you're right. The hydrogen could form on either nitrogen. NH2NH2 will only accept one hydrogen to create a conjugate acid and I'm not sure if it matters which nitrogen it attaches to.
