Laboratory Report O.T Name Date Section DATA FROM EXERCISE 8.4 A. Ability of Buffers to Stabilize the pH of Solutions 1. Enter your data in these spaces pH of distilled water pH of water +1 drop HCI pH of water + 1 drop NaOH: pH of buffer: 7.000 pt of buffer + 1 drop HCt pH5 pH of buffer + 1 drop NaOH pH of buffer +3 drops HCl: p pH of buffer +3 drops NaOH:-p 2. Does your data support the statement thar "buffers help to stabilise the pH of solutions"7 Explain your answer. B. Effect of Exercise on the Rate of ??2 Production 1. Enter your data in these spaces: Time for color change at rest Time for color change after exercise 2. Explain your results C. 1. Role of Carbon Dioxide in the Regulation of Ventilation Enter your data in these spaces: Rate of breathing at rest: Rate of breathing after hyperventilation: breaths/min breaths/min 2. Explain your resultsExplanation / Answer
Acids and bases change the pH of solution.
But when Buffers helps stablizing the pH.
They binds or releases hydrogen ions in response to pH.
We can definitely notice the change that occurs after adding buffers.
Ans(B)..... As we consume more oxgen on exercising we also produce more carbon dioxide because our metabolic rate is elevated.
Ans(C)...... During respiration oxygen and carbon dioxide is exchanged between the body and the environment.
Carbon dioxide is actually a waste product but also is very important as a haemeostatic feedback mechanism.
The level of carbon dioxide in blood is the most influential for ventilation.
The rate of breathing of a normal and healthy person is 12 to 20 breath per minute.
Hyperventilation is the rate or depth of ventilation at abnormal levels causing decreased level of blood carbon dioxide.
In hyperventilation the breathing rate can increase to 25 or even 40 breath per minute.
