Either accept or donate a proton, and K2SO3 is basic ( strong base/weak acid basic! Explanation: An amphoteric substance can act both as an acid in one reaction, and as a base in another reaction. Compare K a2 and K b2 equilibria: HA-can act as an acid or a base 2 2 3 H O A H Oa2 K Dissociation: HA + + + Hydrolysis: HA-will dissociate/hydrolyze to form A 2-and H 2A Approximation: [HA-] F HA-= FNaHA or F KHA 16 Both are strong acids and bases. H2O, NO, CO are neutral oxides. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) Award marks for alternative correct equations such as SO 3 with NaOH. H2SO4 --> H+ + HSO4- <--> 2H+ + SO4 2-. In your case, it will be HSO3^-, but not for the reasons you might think. To tell if K2SO3 (Potassium sulfite) forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralization. Alkaline - Na, Mg Neutral - Al, Si .
