EQUL 499- Det. Of pH of Strong Acid, weak acid, salt, and buffer solution Discussion Topics Discussion Topics (need to submit in Blackboard): 1. What is a buffer? • A buffer is a solution that, when introduced to a new environment, undergoes minimal pH change, typically when adding acidic or basic solutions. These are extremely important for life because the pH of human blood is delicate and even if it is changed by 0.1, there may be catastrophic effects. 2....

1. Write the acid dissociation reaction equation for Na2H2PO4. 2. Write a reaction equation showing how the buffer solution maintains pH ~ 8.0 upon addition of acid. 3. Write a reaction equation showing how the buffer solution maintains pH ~ 8.0 upon addition of a base. Buffer solution: Acid= Na2H2PO4 base Na2HPO4 4. Would you expect this buffer to be better at resisting a change in pH upon addition of acid, or upon addition of base? Why?
