This is a multi-part question. Part 1: Citric acid is a natural
tri-protic organic acid that has the generic formula of H3Cit, with
the following Ka's: Ka1=8.4*10^-4, Ka2=1.8*10^-5, and
Ka3=4.0*10^-6. If you start with a 0.2424 M solution of Na2HCit,
write all of applicable chemical equations and the math equations,
including all equilibria and mass and charge balance, that would be
necessary to solve this?
Part 2: For the same citric acid problem above, what is the pH
of the...
