General Chem Book 1 p320 Passage 2 question 8
Which mixture does not produce a buffer?
A. H3CCO2H with 2 equivalents of H3CCO2K
B. NH3 with 2 equivlanets of NH4Cl
C. H2CO3 1.5 equivalents of KOH
D. H3CNH2 with 1.5 equivalents of HCl
The answer is D. But I think the only solution that makes a buffer is C. How does A and B make a buffer when their conjugate pairs are 1:2 ratios?
