Phosphate

The goal of the lab was to discover the concentration of phosphate in various colas in order to help with a project for a major cola company. Before we could accomplish this final goal, a Spec 20 was used to test three colors of food colorings. A Spec 20 is an instrument used to “measure the intensity of a light beam before and after it passes through a sample and compares these two intensities” (What does a Spectronic 20 measure). The instrument is able to measure the percent transmittance and

High School Department General Science How Does Phosphate Affect the Growth of Aquatic Plants? (A Problem Proposal) I. Introduction Aquatic plants are an important component of lake systems. These plants may be totally submerged beneath the lake surface, floating, or growing along the shoreline. They provide food and shelter for bugs, fish and other organisms, prevent shoreline erosion, filter pollutants from adjacent shoreline activities, and

Rondebosch Introduction: Alkaline phosphatase is a biologically important enzyme, catalysing the hydrolysis of phosphate groups in organic compounds through the process of dephosphorylation. para-Nitrophenylphosphate (pPNP) is an example of a chromogenic substrate of this enzyme, because the product of hydrolysis of pPNP is the yellow para-nitrophenol (pNP) compound along with inorganic phosphate (McComb, Bowers and Posen, 1979). The Michaelis–Menten equation for enzyme kinetics (Murray, 2002) predicts

Estimation of Duckweed Geometric Population Density Phosphate Depletion By Ana Rosina Alarcon University of Texas at El Paso Department of Environmental Science Instructor: Gebregiorgis Alay G. Introduction Duckweed is a small aquatic plant that is able to grow rapidly, making it the ideal specimen for our experiment. It is hypothesized that altering the amount of light received by duckweed will alter its photosynthetic rate. It is predicted that a lower light intensity will

increasing attention in sustainable agriculture (Fayez and Mahmoud, 2006). Phosphorus (P) is one of the major essential macronutrients for plants. In India, it is estimated that there are almost 260 million tons of phosphate rock deposits and this material should provide a cheap source of phosphate fertilizer for crop production (FAI 2002). Although in soil P is available abundantly its bioavailability in soil remains low due to the chemical transformations of P into insoluble forms (Rodríguez and Fraga

and environmental sustainability of the process. Phosphoric acid, also known as orthophosphoric acid, is inorganic compound having chemical formula H3PO4. At room temperate and pressure, phosphoric acid is white, non-toxic and solid compound. Phosphates, a conjugate base of phosphoric acid, are nutritious almost for all life forms, especially for plants. Currently phosphoric acid has a huge variety of applications and uses, including as fertilizer feedstock, synthetic detergents, animal feed additive

We were assigned the ultimate task of finding the phosphoric acid in several rival sodas for this experiment but to get there it required many steps to be taken in advance. As we were a working for a major cola company it was crucial that we were aware of how to use the technology and then more importantly the relationships between all the findings we made through numerous experiments. Our main source of technology was a spectrophotometer so in order to move forward in finding anything out about

Phosphate (PO¬43-) is an element that is very common and essential in the environment and organism lifestyles [1]. The right amount of phosphate deposited in a body of water, will promote growth of organisms that will serve as food for fish. This will in turn, not only increase the number of fish in the water but also allow for better water quality [2]. On the other hand, just like any imbalance in nature, too much phosphate can also become quite harmful. In fact, a high level of phosphate enables

Discussion and Scientific Explanations Goal: This experiment was to find the amount of phosphate in companies cola products. The amount can not be measured directly and therefore must have several experiments conducted to reach the final objective. To find the amount, we had to become comfortable using the spectrophotometer to read the percent transmittance. We also had to find the relation of color, absorption, and the wavelengths of light. We had to use the spectrophotometer 20 for the entire

Biphosphonate used when alkaline phosphates’ is at least twice the upper limit of normal. Edironate slows accelerated bone turnover and is accompanied by symptomatic improvement, less bone pain, and decrease in bone fractures. Initial dose is 5 to 10 mg/kg daily for up to but not exceeding 6 months or 11 to 20 mg/kg not to exceed 3 months. Retreatment for relapse is acceptable only after more than 90 drug free days.
