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
Which of the following mixtures would result in a buffered solution when 1.0 L of each of the two solutions are mixed?
a. 0.2 M HNO3 and 0.4 M NaNO3
b. 0.2 M HNO3 and 0.4 M HF
c. 0.2 M HNO3 and 0.4 M NaF
d. 0.2 M HNO3 and 0.4 M NaOH
