Lab #5: Dissolved Oxygen Lab Be sure to read and understand the below instructions BEFORE the lab! Experiment 1: Investigating the Effect of Temperature and Salinity on the Concentration of Dissolved Oxygen in Water Introduction: In an aquatic environment‚ oxygen must be in a solution in a free state (O2) before it is available for use by organisms (bio-available). Its concentration and distribution in the aquatic environment are directly dependent on chemical and physical factors and are

that less required energy leads to faster rate of reaction. The rate of catalytic reactions is affected by the changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration. Each enzyme has an optimal temperature at which it is most active; the rate of reaction increases with increasing temperature up to the optimal level‚ but drops sharply above that temperature. Most enzymes have their optimal pH value that range from 6 to 8 with exceptions‚ and they may denature in unfavorable pH

bonded to make one product causing an anabolic reaction. There are five factors that effect enzyme activity. They are: ·Temperature ·pH ·Inhibitors ·Substrate Concentration ·Enzyme Concentration The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato‚ you make more Catalase molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between

Hydrogen has a high specific energy‚ high flame speed‚ wide range of flammability‚ and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ICE). These attributes have been realized for more than half a century since the onset of hydrogen engine development. In the early 1990s‚ FSEC conducted research on using hydrogen in an ICE. This work resulted in the development of a mixed fuel called HYTEST. Today‚ automobile manufacturers and DOE continue

report on is oxygen. The name oxygen comes from the Greek word “oxygens‚” which means “acid producer”. Dictionary.com defines oxygen as “a colorless‚ odorless‚ gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature.” Oxygen has many uses today. First‚ oxygen is used by people‚ plants‚ and animals in the respiration process. Tanks of oxygen are used in the healthcare field to treat those who suffer from breathing problems. Oxygen is used as
