Abuffer can be prepared by mixing two solutions. determine if each of the following mixtures will result in a buffer solution or not.
1) mixing 100.0 ml of 0.1 m hf with 100.0 ml of 0.05 m mol kf
a. "yes, it will result in a buffer solution.",
b. "no, it will not result in a buffer solution."
2) mixing 100.0 ml of 0.1 m nh3 with 100.0 ml of 0.1 m nh4br
a. "yes, it will result in a buffer solution.",
b. "no, it will not result in a buffer solution."
3) mixing 100.0 ml of 0.1 m hcn with 100.0 ml of 0.05 m koh
a. "no, it will not result in a buffer solution.",
b. "yes, it will result in a buffer solution."]
4) mixing 100.0 ml of 0.1 m hcl with 100.0 ml of 0.1 m kcl
a. yes, it will result in a buffer solution.",
b. no, it will not result in a buffer solution."]
5) mixing 100.0 ml of 0.1 m hcn with 100.0 ml of 0.1 m koh
a. yes, it will result in a buffer solution.",
b. no, it will not result in a buffer solution.

1) A. "Yes, it will result in a buffer solution."

2) A. "Yes, it will result in a buffer solution."

3) A. "No, it will not result in a buffer solution."

4) B. No, it will not result in a buffer solution."

5) B. No, it will not result in a buffer solution.

Explanation:

A buffer system is formed by two components:

1) Mixing 100.0 mL of 0.1 M HF with 100.0 mL of 0.05 M mol KF. A. "Yes, it will result in a buffer solution."

HF is a weak acid and F⁻ is its conjugate base.

2) Mixing 100.0 mL of 0.1 M NH₃ with 100.0 mL of 0.1 M NH₄Br. A. "Yes, it will result in a buffer solution."

NH₃ is a weak base and NH₄⁺ is its conjugate acid.

3) Mixing 100.0 mL of 0.1 M HCN with 100.0 mL of 0.05 M KOH. A. "No, it will not result in a buffer solution."

It does not have the components of a buffer system.

4) Mixing 100.0 mL of 0.1 M HCl with 100.0 mL of 0.1 M KCl. B. No, it will not result in a buffer solution."

It does not have the components of a buffer system (HCl is a strong acid).

5) Mixing 100.0 mL of 0.1 M HCN with 100.0 mL of 0.1 M KOH. B. No, it will not result in a buffer solution.

It does not have the components of a buffer system.
