HNO2 is a weak acid (pKa = 3.15).

Imagine that you want to prepare pH = 3.15 buffer solution that contains the weak acid (HNO2) and its conjugate base (NO2-). Following is a list of chemical that are available to you in the lab;

H2O, HNO2, KNO2, HCl, NaOH

Which of the following strategies could you use to prepare the targeted buffer solution.

a)Mix 1.0 mol of KNO2 with 0.5 mol HCl in a 100 mL of water

b)Mix 1.0 mol of HNO2 with 0.5 mol HCl in a 100 mL of water

c)Mix 0.5 mol of HNO2 with 0.5 mol KNO2 in a 100 mL of water

d)Mix 1.0 mol of HNO2 with 0.5 mol NaOH in a 100 mL of water
