BR Chem Ch5

Flashcards from chapter 5 of Berkley Review's chemistry book (2010)

QuestionAnswer
Neutralization Mixing of equal mole portions of an acid with a base regardless of their concentration or strength
Equivalence point When you've added same number of moles as you had of the original acid/base
Buffer Roughly equal mole mixture of a weak acid and its weak conjugate base in aq solution. Resists change to pH
Buffer range 10:1 to 1:10 ratios (pKa +/- 1)
Physiological pH 7.4
Half equivalence point pH = pKa
Respiratory acidosis Retention of CO2 (blood pH goes down)
Respiratory alkalosis Loss of CO2 (blood pH goes up)
Metabolic acidosis Loss of HCO3- so blood pH goes down
Metaboli alkalosis Loss of H3O+ so blood pH goes up
Sigmoidal shape of a titration curve
Important polyprotic acids Carbonic acid (H2CO3), phosphoric acid (H3PO4), and sulfuric acid (H2SO4)
Litmus paper Blue turns red under acidic conditions
Choosing indicator * Want pH = pKa +/-1 * approximation: pKa = (pKa_acid + pH_titrantbase)/2
pH at first equivalence point in diprotic acid (pka1 + pka2)/2
Formula weight Find molar mass and divide by number of equivalents
