WebScience Chemistry Sulfurous acid, H2SO3, is a diprotic acid Ka1 = 1.3 × 10-2 and Ka2 = 6.3 × 10-8. The acid forms when sulfur dioxide (a gas with a suffocating odor) dissolves in water. What is the pH of a 0.25 M solution of sulfurous acid? What is the concentration of sulfite ion, SO32-, in the solution? Note that Ka1 is relatively latge. WebWhy is Ka2 ≪ Ka1 for H2SO4 Q. For a polybasic acid, the dissociation constants have different value for each steps, e.g., H3A⇌H++H2A−; K=Ka1 H2A−⇌H++HA2−; K=Ka2 HA2− ⇌H++A3−; K=Ka3 What is the observed trend of dissociation constants in succesive stage? Q. Sulphurous acid (H2SO3) has Ka1=1.7×10−2 and Ka2=6.4×10−8. thalassa schoonhoven

WebDec 9, 2024 · Do we need to calculate Ka and Kb in the final? Ka * Kb = Kw = 1.0 x 10^-14 pKa + pKb = pKw = 14 Ka1 and Ka2 only appear in polyprotic acids (i.e. H2so4). Ka1 is the dissociation constant when 0 H+ are lost, and Ka2 is the disc. when one H+ is lost.
