Coal mining, particularly surface mining, leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite, a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab, you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated.…

Every muscle has lactic acid.According to many people Lactic acid is nasty stuff produced in our muscles during exercise, cause soreness, muscle fatigue, does not contribute to exercise performance, muscle does not use it for fuel, and better athletes makes less of it. But they all are wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion.…

Objective: The purpose of this lab is to analyze enzyme activity at pH neutral for acid phosphatase as the colorless p-nitrophenylphosphate (PNPP) substrate concentration changes. We will empirically determine the concentration of production formation, Vmax and Km from absorbance of yellow PNP in the reaction.…
