Experiment #: 5 
Title: Buffers 
Purpose: The purpose of this lab is to determine how buffers affect the pH of a solution in order 
to observe how a buffer is resistant to pH changes. Additionally, we determined how enzymes 
activity is affected by pH. 
Procedure: 
Part 1: Determine pH of sodium acetate in water & buffer 
1. 2 pH electrodes are place in 2 separate beakers, one filled with tap water & one is filled 
with a pH 7 buffer (both have an approximate pH of 7) 
2. A scoop of sodium aceta...

Answer: Trache 
a 
Correct 
Answer: Alveoli 
Response 
Feedback: 
The alveoli allow air to come in indirect contact with the 
bloodstream through the pulmonary capillary system. 
This alveolar membrane, which is one cell thick, allows 
carbon dioxide to diffuse into the alveoli from the 
bloodstream and oxygen to diffuse to the bloodstream ...
