Answer 1

Answer:

4. option , acid H+ and conjugate OH-

Answer 2

pH OF BUFFER SOLUTION

The pH of buffer solution depends on concentration of (D) Acid H+ and conjugate base OH-

EXPLANATION:

*Due to the presence of equilibrium between the acid and its conjugate base, buffer solutions are resistant to pH changes.

*When strong acid is introduced to a buffer, the equilibrium shifts to the left, and the hydrogen ion concentration rises less than predicted for the amount of strong acid supplied.

*Buffers may be made in a variety of ways by combining an acid and its conjugate base in a solution.
