Question

Which of the following is TRUE? Group of answer choices a,A buffer is most resistant to pH change when [acid] = [conjugate base] b.An effective buffer has very small absolute concentrations of acid and conjugate base. c.None of the above are true. d.A buffer can not be destroyed by adding too much strong base. e.It can only be destroyed by adding too much strong acid. f.An effective buffer has a [base]/[acid] ratio in the range of 10 - 100.

Answer 1

a. a buffer is most resistant to pH change when [acid] = [conjugate base]

Step-by-step explanation:

A buffer consists of a weak acid and its conjugate base or a weak base and its conjugate acid, therefore the concentrations of the acid and its conjugate base must be the same to resist more the change in pH.
