Which of the following statements are not true about buffer solutions?

Question 32 options:

The closer the ratio of concentration weak acid/base to the concentration of salt of its conjugate base/acid, the less effective the buffer to resist pH change.


Buffer has acid and base components that can work specifically to resist pH change.


A buffer solution can be prepared by mixing a weak acid and salt of its conjugated base or by mixing a weak base with salt of its conjugated acid.


pH of a buffer solution will not change despite the addition of small quantities of acid or base.
