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
