1.) Which one is the stronger Bronsted base, respectively? (Use pKa values of the conjugate acid.) a) Cl or Br b) O2 or S2- c) H2O or NH3 d) HCOs or COs 2.) Order the acids according to their increasing strength: a) Fe(OH2)s3*, [Li(OH2)s], [Mg(OH)]2, b) H2S04 and H2SO3 3.) Complete and balance the following acid-base reactions: a) CaO + HBr b) Th0s + H2SO4 c) P2Os +H20 d) Be(OH)2 + H' + H2O e) B(OH)3 + H f) [Fe(OH2)6]2+-KOH â â 4. Complete and balance the following reactions and identify which of the reagents, respectively, is the Lewis acid and which one is a Lewis base: a) SO2 + N(CH3)3 b) KF + BF3 c) Cr(CN)2 + KCN d) Ca(OH)2 +CO2 â 5.
