KNES 470 Dr Rubin 4-18-12 Sodium Bicarbonate and Boxing Performance Boxing is a sport which relies on anaerobic power since it contains short-duration and high intensity work. A typical boxing match today consists of 3 minute rounds with a 1 minute seated recovery rest. When an athlete performs exercise at maximal level for more than 30 seconds‚ most of the energy comes from anaerobic glycolysis. During this process‚ lactic acid is produced which causes a decrease in pH levels within the muscle

Analysis of Soda Ash and Carbonate-Bicarbonate Mixture Submitted: February 27‚ 2013 Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas España‚ Manila Abstract A standard acid solution like HCl can be used as titrant for the analysis of both soda ash and a carbonate-bicarbonate mixture. In the analysis of soda ash‚ the volume needed to neutralize the soda ash is used to compute for its alkalinity‚ in this experiment we obtained a 17.6 % alkalinity with an error

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any

William Piumbroeck Chem 214 Acid-Base Titration‚ Determination of Carbonate and Bicarbonate in a water sample Introduction The purpose of this lab is to determine the concentration of two bases‚ carbonate and bicarbonate‚ by using a potentiometric titration. We can determine the concentration of the bases in the reactions ( H+ +CO3- < ==> HCO3- and H+ + HCO3- < ==> H2CO3-) by the way the pH of the solution changes. The way the pH changes when a strong acid is added can

Buffer systems * prevent major changes in pH of body fluids by removing or releasing H+ * act quickly to prevent excessive changes in H+ concentration. Body’s major extracellular buffer system is “bicarbonate-carbonic acid buffer system”. There are 20 parts of (HCO3) to one part of (H2CO3). ---- [20:1]. When the ratio is no longer maintained‚ it will result to acid-base imbalance. Carbon dioxide is a potential acid; when dissolved in water‚ it becomes carbonic acid. Lungs under the

causes * One key to distinguish between respiratory and metabolic acidosis is that in respiratory acidosis‚ the CO2 is increased while the bicarbonate is either normal (uncompensated) or increased (compensated). Compensation occurs if respiratory acidosis is present‚ and a chronic phase is entered with partial buffering of the acidosis through renal bicarbonate retention.* * Respiratory acidosis results from a build-up of carbon dioxide in the blood (hypercapnia) due to hypoventilation.
