Uplоаd аn imаge оf yоur answers to this question. If you decided to use a PIPES buffer (piperazine-N,N’-bis(2-ethanesulfonic acid)) instead of the HEPES buffer used in this procedure, how many moles of the protonated form of PIPES and how many moles of deprotonated form of PIPES would you have to add to 1.0 liter of water to prepare a 0.10 M PIPES buffer at pH 7.5? The appropriate pKa is 6.76. Show your work for full or partial credit. (Note: The sulfonic acid portion of the molecule is a strong acid and hence, fully deprotonated at pH 7.5.)
