You have a solution of 100 M NaOH sitting on the bench. What will be the dilution factor in order to achieve a final concentration of 200 pM NaOH. Which weak acid/conjugate base pair would make the best buffer at pH 8.8? Question 2 options: a. HEPESH+/HEPES, pKa = 8.08 b. Acetic acid/acetate, pka = 4.76 d. NH4+/NH3, pka = 9.25 e. Succinic acid/succinate, pka = 4.21 c. Dihydrogen phosphate/hydrogen phosphate, pka = 7.2 You have a solution of 100 M NaOH sitting on the bench.
