Recall from Chapter 4 that the acidic proton in virtually all oxoacids is bonded to one of the oxygen atoms of the oxoanion. No acid stronger than \(H_3O^+\) and no base stronger than \(OH^\) can exist in aqueous solution, leading to the phenomenon known as the leveling effect. How do you ensure that a red herring doesn't violate Chekhov's gun? Solved Sulfurous acid, H2SO3, dissociates in water in two - Chegg Which acid and base react to form water and sodium sulfate? Consider \(H_2SO_4\), for example: \[HSO^_{4 (aq)} \ce{ <=>>} SO^{2}_{4(aq)}+H^+_{(aq)} \;\;\; pK_a=-2 \nonumber \]. Each acid and each base has an associated ionization constant that corresponds to its acid or base strength. Consequently, it is impossible to distinguish between the strengths of acids such as HI and HNO3 in aqueous solution, and an alternative approach must be used to determine their relative acid strengths.

Thus the conjugate base of a strong acid is a very weak base, and the conjugate base of a very weak acid is a strong base. Write and balance the equation for the reaction of hydrochloric acid (H2SO4) and sodium hydroxide to produce sodium sulfate and water. Dissolved in water, sulfur dioxide is slowly oxidized to sulfur trioxide (SO3) and then turned into sulfuric acid.
