Which of the following statements about buffered solutions are true? Select all that apply. Buffer solutions resist changes in the concentration of hydroxide ions. A buffer solution may be made up of a strong acid and one of its salts. Buffer solutions will not change very much if a small amount of strong acid is ad ed to it. Buffer solutions will not change pH very much if a small amount of weak base is added to it.
