Discuss how buffers help to regulate body pH. The pH level in the blood is maintained by the kidneys and the lungs. The pH level on the blood should be at 7.4. In order for the kidneys and lungs to maintain this pH level it affects the buffers in the blood. The buffer is a substance that is resistant to the change in the body’s pH level. Basically the buffers can make an acid or base less potent and try and neutralize it so the body is not overly acidic or basic. When these buffers attach to the

tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions‚ measurements‚ and weights to then calculate using algebraic formula. Throughout lab one we were introduced to many different forms of measurement‚ whether its using a ruler too measure length‚ a digital scale to measure weight‚ and also many different sized and shaped flasks to measure different volumes. Another key

Conclusion Both Kool Aid and Gatorade contain buffers. For the buffer in Kool Aid‚ pKa1 ≈ 3.70‚ pKa2 ≈ 4.90‚ pKa3 ≈ 6.50 and for the buffer in Gatorade‚ pKa1 ≈ 4.50‚ pKa2 ≈ 5.40‚ pKa3 ≈ 6.70. Discussion of Theory A buffer capacity is the maximum amount of hyrdrogen or hydroxide ion that can be added to a buffered solution before a significant change in the pH occurs. Increasing the concentration of the buffer can increase the buffer capacity of a solution. At the half equivalence point‚ the moles

t Design and preparation of buffers effective at different pHs Abstract These experiments aimed to determine the optimum pH ranges various buffers are effective and provide opportunity for the use of the Henderson-Hasselbalch equation to prepare a buffer of a specific pH. Three different buffer systems were initially investigated; volumes of weak acid and weak bases of specified concentration were prepared and titrated against strong acid or strong base solutions with pH readings taken at frequent

Argument for using a computer With the popularity of computers‚ almost every family has one computer. Some parents‚ for various reasons‚ let children use computers for learning‚ relaxing‚ and so on. However‚ children between ages of 6 and 16 are in the growth stage.
