1. Which of the following solutions would be a buffer? Select all that apply.
- a solution containing HNO2 and LiNO2
- a solution containing NH3 and NH4+
- a solution containing HCl and NaCl
- a solution containing HClO4 and NaClO4
- a solution containing HF and HCl
- a solution containing HN3 and NaN3
Homework Answers
According to the condition given in question, A buffer solution is an aqueous solution consists of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It has the property that the pH of the solution changes very little when a small amount of strong acid or base is added to it.
So from the above solutions, the buffer solutions are
a solution containing HNO2 and LiNO2
reason: it is mixture of Weak acid(HNO2)and its conjugate base
(LiNO2). So it isacts as a Buffer solution .
a solution containing HN3 and NaN3
reaon: it is a mixture of weak acid and strong base
a solution containing NH3 and NH4+
Reason : NH3 and its conjugate acid,
NH4+. When HCl (strong acid) is added to this
buffer system, the extra H+ ions added to the
system are consumed by the NH3 to form
NH4+
