Acid Substance or Species HE HNO2 CH3COOH HOCI HOBI ka = 7.2 x 10-4 NH3 K = 4.5 x 10-4 (CH3)3N = 1.8 x 10-5 [Co(OH)]2+ Ka = 3.5 x 10-8 [Fe(OH2)2]2+ Ka = 2.5 x 10-9 [Fe(OH2)613+ Ka = 3.5 x 10-4 [Be(OH)412+ Ka = 4.0 x 10–10 [Cu(OH)212+ Ka1 = very large HBO2 Ka2 = 1.2 x 10-2 (COOH)2 HOCN HCN H2SO4 Kb = 1.8 x 10-5 Kb = 7.4 x 10-5 Ka = 5.0 x 10-10 Ka...
What is the pH of a 0.2 M CH3CH2NH3(BrO) solution? Kb(ethylamine CH3CH2NH2)=4.3 x 10^-4 Ka (HBrO) = 2.3 x 10^-9 The answer is "pH 11", but I keep getting 11.96. (i compared Ka to kb and used Kb since it is bigger) then solved for pH using only Kb. Please explain the correct way of doing it if i was doing it wrong. thanks!
