Statement 1 is true because acetic acid and sodium acetate together form a buffer solution. Statement 2 is false because hydrochloric acid is a strong acid and sodium chloride is a salt, therefore they cannot form a buffer solution. Statement 3 is true because a buffer solution is able to resist changes in pH when small amounts of acid or base are added.
