# of deprotonation steps in solution make buffer stronger?

Postby Chem_Mod » Sun Aug 21, 2011 12:33 pm

Question: Does the number of deprotonation steps in solution make a given buffer inherently stronger, i.e. a H3PO4 & Na3PO4 buffer or H2CO3 & Na2CO3? Also, do these steps always require water, or can other solvents be used to achieve the same effect?

Answer: No, extra deprotonation steps just give the buffer more ranges in which to be used. Nonpolar solvents like hexane and toluene are not effective as proton donors/acceptors, but there are plenty of other polar (protic and aprotic) solvents that have acid/base reactivity
