Since H2S is one of the seven strong acids, HS- is a negligible base. more $\ce{SO4^{2-}}$ should mean a shift to the left, producing more $\ce{HSO4-}$ and $\ce{H2O}$. acid, HSO4-; base, H2O. Hydroiodic acid. It is a conjugate base of a sulfuric acid. Conjugate Acid-Base Pair: An acid either loses a proton or accepts a lone pair of electrons to form a species called its conjugate base. The species H2O, HCO3^-, HSO4^- and NH3 can act both as Bronsted acids and bases. Cl-Chloride. They work because the acidic species neutralize the OH-ions while the basic species neutralize the H + ions. (a) Write the formula for the conjugate base of this acid. Which acids are strong? If a substance behaves both as an acid and as a base, then the substance is Amphoteric in nature. Acid, Base, Conjugate Acid, Conjugate Base. HSO4^- + BrO^- ==> HBrO + SO4^2-So the pairs are HSO4^- and SO4^2-with the other pair BrO^- and HBrO. H2SO4 is a strong acid and completely dissociates to form H+ and HSO4-. I-Iodide.
