Question 3 1 pts Which statement accurately describes what happens in a buffer solution when you add strong acid or strong base? The strong species is converted to weak species by reaction The pH change is smaller than you expect based on the amount of acid or base added Two reactions occurs-first a completion reaction, then an equilibrium reaction All three statements above accurately describe this situation Question 4 Can you create a buffer by mixing HNO3 with KOH? Yes-...
