Bronsted-Lowry/Lewis Acids & Bases Bronsted-Lowry definition • —acid: H+ donor —base: H+ acceptor • Lewis definition —acid: electron acceptor —base: electron donor • H+ attaches to H2O to form a hydronium H3O+ ion • strong acids and bases completely dissociate in water and have huge K values • weak acids and bases partially dissociate in water • important strong acids —HCl —HBr —HI —HNO3 —HClO4 —H2SO4 • important strong bases —LiOH —NaOH —KOH —Ca(OH)2 —Ba(OH)2 —Sr(OH)2 • conjugate acid - add one H+ —ex. conjugate acid of H2O is H3O+ • conjugate base - remove one H+ —ex. conjugate base of H2O is OH- Structure, Acidity/Basicity, & pH • ex. HClO vs HClO2 Electron density distributed across Cl and O atoms Electron density distributed across Cl and two O atoms, resulting in more stable acid and conjugate base • the higher the electronegativity of the atoms in an acid, the higher the Ka will be • autoionization of water: H2O(l)(acid) + H2O(l)(base)⁶H3O+(aq) + OH-(aq) —water functions as an acid and a base —H3O+ is conjugate acid and OH- is conjugate base • equilibrium constant for water: Kw = [H3O+][OH-] —Kw = 1.00 x 10^-14 M at standard temp and pressure —[H3O+] = [OH-] = 1.00 x 10^-7 M at standard temp and pressure • equations for pH/pOH and concentration —pH = -log[H3O+] or pOH = -log[OH-] —[H3O+] = 10^-pH or [OH-] = 10^-pOH —pH + pOH = 14 • some pH values —blood = 7.4 —rainwater = 5.6 —1 M NaOH = 14 —1 M HCl = 0 • ex. If the pH of blood is 7.4 and the pH of milk is 6.5, how much more acidic is milk than blood? —10^-6.5 M = 10^0.9 = 10 (rounded) 10^-7.4 M —milk is about 10 times more acidic than blood or blood is about 10 times more basic than milk —think of acidity in terms of [H3O+] and basicity in terms of [OH-] • pKw = -log(Kw) = 14 at 25˚C
