Weak Acids Protonate all those polyprotic anions Sulfite SO3 (2+) H2SO3 (sulfurous acid) Nitrate nitric acid Organic: carboxylic acids R group + carboxylic acid Functional group should be identified, CH3, CH2 R-COOH  R – COO- + H+ …..ic acid …..ate R-COO- = conjugate base of a weak acid. To get THIS only into the solution, get it as a salt, or pair with a cation. Usually Na+ or K+ CH3COO- K + Acetate ion , salt : cation 1 st , then anion KCH3COO : Potassium acetate, salt of a weak acid Bases : weak bases Most of these are AmInEs. [derivatives of ammonia, NH3]. When ammonia is protonated,

Unformatted text preview: NH4, conjugate acid. R- NH2. Methyl group = R, then its called methyl amine. Take trimethylamine, proponate it (add H), then . . trimethylammonium[base] B = base , BH+ = conjugate acid. C5H5N Pyridine : makes it a base. INE ending = base. Conj. Acid, C5H5NH+ : pyridinium. To get a salt, get an anion, like Chrloride or Bromide. Methyl ammonium chloride CH3NH3CL is mixed at 0.035 Molar, whats the PH?...
