The conjugate base of any acid HAHA simply the acid MINUS a proton, H^+H+; when we do this for HAHA we get A^-A−. Likewise the conjugate acid of any base A^-A− is simply the base plus a proton, H^+H+, to give HAHA. Mass and charge are conserved.
To use sulfuric acid as an example, we start with the H_2SO_4H2SO4 formula; less a proton, this gives HSO_4^-HSO−4 as the conjugate base, and the conjugate base of "bisulfate"bisulfate is "sulfate"sulfate ion, SO_4^(2-)SO2−4. All I am doing is exchanging protons, H^+H+, and conserving mass and charge.
Can you tell the conjugate bases of the following acids: HClO_4HClO4; H_3PO_4H3PO4; NH_4^+NH+4; NH_3NH3; NH_2^-NH−2; HC-=CHHC≡CH; NH^(2-)NH2−?
