Keep in mind, though, that free \(H^+\) does not exist in aqueous solutions and that a proton is transferred to \(H_2O\) in all acid ionization reactions to form hydronium ions, \(H_3O^+\). As we noted earlier, because water is the solvent, it has an activity equal to 1, so the \([H_2O]\) term in Equation \(\ref{16.5.2}\) is actually the \(\textit{a}_{H_2O}\), which is equal to 1.

Sulfurous acid is a corrosive chemical and b) How many electrons are transferred in the reaction? You will notice in Table \(\PageIndex{1}\) that acids like \(H_2SO_4\) and \(HNO_3\) lie above the hydronium ion, meaning that they have \(pK_a\) values less than zero and are stronger acids than the \(H_3O^+\) ion.

HNO3 - this is a strong acid and dissociation equation is HNO3 (aq) H+ (aq) + NO3- (aq) H2SO4 - This is not so simple: H2SO4 is a diprotic acid . Recall from Chapter 4 that the acidic proton in virtually all oxoacids is bonded to one of the oxygen atoms of the oxoanion. Once again, the activity of water has a value of 1, so water does not appear in the equilibrium constant expression. Part AGiven that sulfurous acid dissociates in water in two stepsAccording to given data First equivalence point is at 100mL and Half equivalence for. -3 Balance this equation.

Sulfurous acid, H2SO3, is a weak diprotic acid with acid-dissociation constants: Ka 1 =1.210-2 Ka 2 =6.210-8. We can use the relative strengths of acids and bases to predict the direction of an acidbase reaction by following a single rule: an acidbase equilibrium always favors the side with the weaker acid and base, as indicated by these arrows: \[\text{stronger acid + stronger base} \ce{ <=>>} \text{weaker acid + weaker base} \nonumber \]. This equilibrium constant is a quantitative measure of the strength of an acid in a solution. The equilibrium in the first reaction lies far to the right, consistent with \(H_2SO_4\) being a strong acid. The equilibrium constant for this dissociation is as follows: \[K=\dfrac{[H_3O^+][A^]}{[H_2O][HA]} \label{16.5.2} \].
