Buffer systems, Chemistry IA

Recommended Posts


For my chemistry IA, I'm doing it on whether temperature affects buffer capacity, and the buffer solution I'm experimenting with the McIlvaine Buffer. And I know, I'm so stupid for using this buffer cause there's barely any information on it. I was wondering if anybody would know what the equilibrium chemical equation for it would be? 

I'm a little confused as to how it would work when there's citric acid (C6H8O7and disodium hydrogen phosphate (Na2HPO4) and then add sodium hydroxide (NaOH) to it as the titrant. 

I understand the basic buffer equation, with a weak acid and it's conjugate base in equilibrium and hydrogen ions floating around that then react with added strong bases, but since this buffer has disodium hydrogen phosphate in it as well as citric acid, I'm not entirely sure how it works. 

Any help would be much appreciated! Thank you so much.
