Sulfurous acid, H2SO3, dissociates in water in two steps: H2SO3 + H2O <---> H3O+ + HSO3- ; Ka1 = [H3O+] [HSO3-] / [H2SO3] HSO3- + H2O <---> H3O+ + SO3^2- ; Ka2 = [H3O+] [SO3^2-] / [HSO3-] A 150mL sample of H2SO3 was titrated with 0.10M NaOH. [H3O+][SO3^2-] / [HSO3-] Click Start Quiz to begin! until experimental values are available. Consequently, the proton-transfer equilibria for these strong acids lie far to the right, and adding any of the common strong acids to water results in an essentially stoichiometric reaction of the acid with water to form a solution of the \(H_3O^+\) ion and the conjugate base of the acid.

Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. "Use chemical equations to prove that H2SO3 is stronger than H2S." III. If we are given any one of these four quantities for an acid or a base (\(K_a\), \(pK_a\), \(K_b\), or \(pK_b\)), we can calculate the other three. Using first-principles simulations, we show that HOSO displays an unforeseen strong acidity (pK = 1) comparable with that of nitric acid and is fully dissociated at the airwater interface. Since we have a two substances combining, SO2 + H2O = H2SO3 is a Synthesis Reaction (also called a Combination Reaction" reaction). Goldberg, R. N. and Parker, V.
