A buffer contains significant amounts of a weak acid and a salt containing its conjugate base. The acid consumes any added base, and the base consumes any added acid. In this way, a buffer resists pH change. Strong acids, strong bases, two bases, or two acids cannot form a buffer on their own.

Which set of compounds would form a buffer in aqueous solution?

State which one is a buffer or not a buffer:

a) NaCl and KCl

b) HCN and NaF

c) NaBr and KBr

d) HCOOH and HCOOK

e) KF and KOH

f) HBr and NaBr

g) HCN and KCN
