a buffer can be made by mixing select one: a strong acid and strong base. a weak base and a transition metal. a weak acid and its conjugate base. a metal cation and a ligand.



Answer :

A buffer solution, also known as a buffer, is a mixture of a weak acid and its conjugate base (or a mixture of a weak base and its conjugate acid). Solutions with buffers thwart changes.

buffer is an aqueous solution made up of a weak base and its salt (base buffer) or an acid and its salt (acid buffer) (basic buffer). It is used to stop pH fluctuations in solutions because the pH of a small amount of strong acid or base added to it changes very little. On Adding Base and Acid. 1. When acid is added, the acetate ions take away the acid's released protons, forming an acetic acid molecule.
