Question

Which of the following solutions is a good buffer system? a solution that is 0.10 M NaOH and 0.10 M KOH a solution that is 0.10 M HI and 0.10 M NH4+ a solution that is 0.10 M HC2H3O2 and 0.10 M LiC2H3O2 a solution that is 0.10 M HBr and 0.10 M KC2H3O2

Answer 1

Hey there!:

Option: C) a solution that is 0.10 M HC₂H₃O₂and 0.10 M LiC₂H₃O₂

Reason : Buffer mixture means mixture of either weak acid and salt of weak acid or weak base and salt of weak base.

Here acetic acid is a weak acid and its Li salt

Hope that helps!
