MODULE 8: TEXTBOOK NOTES (CHAPTERS 9, 10 and 11) CHAPTER 9 → MONOPROTIC ACIDS AND BASES IN AQUEOUS SOLUTIONS The solvent is both acidic and basic: 2H O ⇌ H O+ + OH- K = 1.0x10-14 at 25℃ pKw = -logKw = 14 Is activity important? - Activity can be important. Normally we neglect activities in pH calculations unless it is clearly needed (ex. Titration in a 0.1M salt solution which we will not be considering) At 25℃ neutral pH (=-log[H+]) = 7 because [H+]=[OH-] = √Kw...
