WE DO:

A buffer system composed of H_{2}*S and NaHS was created by dissolving 3.00 moles of each into 1.00 L of solution.

A) Draw an image to represent the buffer system. (Include spectator ions, you do not need to include water)

Key

H_{2}*S

N a^ -

0

HS

B) Write the reaction that would take place if a strong acid ( H_{3} O^ + ) were added to the system.

C) Write the reaction that would take place if a strong base (OH-) were added to the system.
