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....
