3. Some molecules and ions are amphoteric or amphiproti c, meaning that they can react either as an acid or as a base: HCO 3 - + OH - n CO 3 - 2 + H 2 O HCO 3 - + H 3 O + n H 2 CO 3 + H 2 O What else, that we use a lot, is amphoteric? _____________ Its CA is _____________, its CB is _____________ 4. Chemical Equations, when using Bronsted concepts, are naturally Net Ionic . Express all acids and bases are written as they exist

Unformatted text preview: . Then, just transfer a proton! (a) HAc(aq) reacts with NaOH(aq). (b) HCl(aq) reacts with NH 3 (aq) Why do we prefer to show H + (aq) as H 3 O + ? 5. Weak Acid Problem : For 0.15 M HClO 2 (Ka = 1.1 x 10-2 ) what are the […] and pH? [HClO 2 ] = _________ [H 3 O + ] = [ClO 2-] = _________ pH = __________ 6. Combining Chemical Equations and Their K Values . (this is something like a Hess’s Law calculation) (a) For A B K 1 = ] A [ ] B [ B C K 2 = ] B [ ] C [ A C K 3 = ] A [ ] C [ (b) Given: 2 SO 3 2 SO 2 + O 2 K = 0.21 (at 700 °C) 2 NO 2 2 NO + O 2 K = 16. Find K for: SO 2 + NO 2 SO 3 + NO K = _____________...
