I. INTRODUCTION:
A.PURPOSE:
a. To define and understand the key terms. ~acid ~buffer system ~base ~acidosis ~pH ~alkalosis ~pH scale ~hypoventilation ~pH indicators ~hyperventilation b. To determine the acidic or base nature and actual pH of various substances. c. To discuss the formation of the carbonic acid/bicarbonate ion buffer system in maintaining homeostasis, especially with regard to ventilation.
B. BACKGROUND: Homeostasis is the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function. This is essential for the human life. Every piece of this experiment was to prove the slightest change can through your body off balance. Acids are a subject that reacts to a base. A base is a substance that can accept hydrogen ions (protons). These two components together help the human body to stay balanced. The pH scale will help determine which direction the body is leaning towards; the base or the acid. The body has a buffering system to help regulate the process.
To help you better understand the pH in different substances please look at the below table. The pH of Some Common Substances | Increasing pH (Decreasing Acidity) | Substances | 0 (most acidic) | Hydrochloric acid (HCl) | 1 | Stomach acid | 2 | Lemon juice | 3 | Cola, beer, vinegar | 4 | Tomatoes | 4.5 | Fish die if water is this acidic | 5 | Coffee | 5.5 | Normal rainwater | 6 | Urine | 6.5 | Saliva | 7 (neutral) | Water, tears | 7.5 | Human blood | 8 | Seawater | 9 | Baking soda, antacids | 10 | Great Salt Lake | 11 | Ammonia | 12 | Bicarbonate of soda | 13 | Oven cleaner | 14 (most
