QUESTIONS 1. Consider the buffer mixture that you created in Part C.1 of the procedure. a. How many moles of NaC,H,O, are contained in 12 mL of buffer? b. How many moles of HCI would need to be added to 12 mL of buffer to destroy the system (.e., completely neutralize the base in the buffer)? c. How many mL of 3.0 M HCl would be needed to destroy 12 mL of the buffer system? 2. State whether each of...
