8. Which of the following is TRUE about buffer solution?a. pH of buffer solution will never change despite addition of small amount of baseor acidb. Buffer can be made by mixing strong acid and salt ot its conjugate base or bymixing strong base with salt of its conjugate acidc. Buffer has acid and base components that can work specifically to resist pHcharged. The closer the ratio of a concentration, weak acid/base to the concentration of saltof its conjugate base/acid, the less effective the buffer to resist pH charge9. What can be Statement can be TRUE about acidic buffer?a. It is made of a mixture odf strong acid and salt of its conjugate acidb.
