FREE Expert Solution

Recall 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


NaF and KF

NaF → salt
KF → salt
mo weak acid present 

Not a buffer


NaCl and KCl

NaCl → salt
KCl → salt
mo weak acid present 

Not a buffer


HCl and KCl

HCl → strong acid
KCl → salt (KCl → K+ + Cl-)
strong acid + conjugate base

Not a buffer


HF and NaF

HF → weak acid
