Q. Sulphurous acid (H2SO3) has Ka1=1.7×10−2 and Ka2=6.4×10−8.
WebOct 18, 2007 · For the triprotic acid, phosphoric acid, H3PO4, there are Ka1, Ka2, and Ka3. And we know from the book that the value of Ka3 is too small, so we neglect the [H+] contribution from it. Normally, we encounter questions involving pH calculations of neutralization of a diprotic acid and a base, for example, H2SO4 and NaOH. WebHSO 4- ⇌ H + + SSO 42- How to find pH for these two cases? Case 1: Finding pH for case 1 is easy. Find H+ concentration and substitute it to pH equation. H + concentration = H 2 SO 4 concentration * 2 H + concentration = 0.00896 * 2 H + concentration = 0.01792 M pH = -log [H+] pH = -log [0.01792] pH = 1.74
