H2so3 pka value
WebSO 2 + OH – = HSO 3– HSO 3– is the conjugate base of sulfurous acid having pka 6.97, so it is less basic as well as less acidic. As HSO 3– is a very weak acid so its conjugate base is SO 32-. HSO 3– = H + + SO 3– Bisulfite is also a good reducing agent, it can give hydrogen easily. 2HSO −3 + O 2 → 2SO 2−4 + 2H + 1. WebAnd we know that the equilibrium, the equilibrium favors the acid with the higher pKa value, favors the formation of the acid with the higher pKa value. And it's a little bit tricky cause we have two negative values for our pKa. But negative two is closer to zero than negative three, so negative two is the higher pKa.
