For this problem, find which of the following combinations cannot produce a buffer solutionRecall that a buffer can be composed of the following:• weak base and its conjugate acid• weak acid and its conjugate base• weak acid and a strong base ▪ concentration of weak acid > concentration of strong base• weak base and a strong acid ▪ concentration of weak base > concentration of strong acid[readmore]a. H2SO4 and Na2SO4 • H2SO4  →  strong acid (must be paired with a weak base)• Na2SO4 →  salt of a strong acid → neutral salt • not a good buffer systemb. HClO4 and NaClO4• HClO4  →  strong acid (must be paired with a weak base)• NaClO4 → salt of a strong acid → neutral salt • not a good buffer systemc. HF and NaF • HF→ weak acid• NaF breaks up in the solution as Na+  and F-  HF       +      H2O       →       H3O+      +         F-(weak acid)                                            (conjugate base)• weak acid + conjugate base = buffer• the solution is a good buffer systemTherefore, H2SO4 & Na2SO4 and HClO4 & NaClO4 cannot make a buffer system
