Question

Which of the following can be used as a buffer solution?
O A solution containing NaCl and NaOH.
A solution containing NaCl and NHLOH
A solution containing sodium acetate.
O A solution containing ammonium acetate.​

Answer 1

Answer:

A solution contain NaCL and NaOH.

Answer 2

Explanation:

Buffers work well only for limited amounts of added strong acid or base. Once either solute is completely reacted, the solution is no longer a buffer, and rapid changes in pH may occur. We say that a buffer has a certain capacity. Buffers that have more solute dissolved in them to start with have larger capacities, as might be expected.

1)no.

2) I don't know about NHLOH.

3)Buffer solution.

A solution of sodium acetate (a basic salt of acetic acid) and acetic acid can act as a buffer to keep a relatively constant pH level. This is useful especially in biochemical applications where reactions are pH-dependent in a mildly acidic range (pH 4–6).

4)A solution of sodium acetate and ammonium acetate can act as a buffer.

Reason: A buffer solution consists of a mixture of a weak acid and its conjugate base or vice versa

3and 4 can be used as a buffer solutions.
