Question

A) 0.365M HC2H3O2 and 0.497 M NaC2H3O2

B) 0.121 M HC2H3O2 and 0.116 M NaC2H3O2

C) 0.821 M HC2H3O2 and 0.713 M NaC2H3O2

D) 0.521 M HC2H3O2 and 0.217 M NaC2H3O2

is it c?????

Answer 1

hmm...i'm feeling really lazy to calculate. but, just find the ratio between the base and the acid. the closer the ratio is to one, the higher the buffering capacity
