  • Phosphorus: German Alchemist Hennig Brandt

    Phosphorus was discovered by the German alchemist Hennig Brandt, in 1669. In a surely arduous process, Brandt heated and processed 50 to 60 buckets, per experiment, of urine until he isolated a substance he named ‘light-bearer’ or phosphorus. Each of these experiments could take two weeks. He would let these buckets of urine stand until they ‘bred worms’. Brandt would then boil the urine with sand, and this is how he distilled elemental phosphorus. This discovery is also notable, aside from discovering phosphorus of course, because this was the first time we had discovered an element not known to ancient peoples. Brandt, also called the last alchemist, kept it a secret, thinking he had found something that could change base metals into gold,…

  • The Importance Of Phosphites During WWII

    Where did phosphite come from? During WWII, rock phosphate was used as a white phosphorus incendiary and smoke screen. The shortage of rock phosphate concerned ag-officials and they began to look for alternative sources of phosphorus fertilizers. As a result, phosphonates were first considered as fertilizers in Germany and the United States during the 1930s and '40s. Rock phosphate is the beginning of most commercially made phosphorus products in the market today. Without the phosphate, many…

  • Pepsi Experiment Lab Report

    levels of phosphoric acid in the undiluted Pepsi-Cola were calculated using Equation 1, P/ppm=(Diluted P/ppm )((Total Vol Dil Sample/ g)/(Mass soda / g))(15/10) (1) In Equation 1, P/ppm is representative of the phosphorus content in Pepsi-Cola, 15 represents the sum volume of U1 and the color reagent, and 10 represents the volume of U1. Figure 1 shows the regression model of the found calibration results (ppmP versus the absorbance/AU at…

  • Phosphorus Lab

    During this lab, my main goal was to discover exactly how much phosphorus (or phosphate) is in the composition of plant food, or in the case of the Guided Inquiry portion of the lab, in two different brands of plant food. If I put it in the most concise way possible, to do this, I carried out quite a few processes that caused the components of the plant food to separate from each other. Basically, I got the phosphorus, along with some other substances, to form as a precipitate. Next, through a…

  • Phosphorus Transition

    environmental media Generally, Phosphorus enters the environment through three basic pathways; Air, Water, and Soil. Specifically in the Watershed Nature Centre, Phosphorus is observed to be leached through the soil and resident in the water sediment with periodical release into the water body. a. Air In general, phosphorus is not likely to spread, because it reacts with oxygen fairly quickly. When phosphorus ends up in air through exhausts it will usually react with oxygen right away to be…

  • Phosphorus Cycle

    five cycles we studied were: the water cycles, the carbon cycle, the nitrogen cycle, the phosphorus/ rock cycles, and the sulfur cycle. First I will describe how the water (hydrologic) cycle contributed to resource sustainability and to continue…

  • Phosphorus Recovery Essay

    3.2. Phosphorus recovery in MEC When the pH of the cathode chamber reached 8, P started to precipitate as struvite. The reactor accomplished a peak precipitation efficiency of 94%. Recovery of P was in the cathode chamber, where the neutral solution was converted to alkaline by proton consumption. Previous studies reported similar results, like Cusick et al. (2014) and You et al. (2016), where high P removal was carried out by MEC (85%) and MFC (82%), respectively. Cathode pH was affected by…

  • Phosphorus Analysis Lab

    samples allowed for the synthesis of a metal complex. In part two of the experiment we used a procedure similar to part one in order to collect phosphorus out of a sample of fertilizer. This sample was then compared to the amount of phosphorus which was present in the NPK ratio for that fertilizer. Part one of the experiment was based entirely on the collection of the total mass for the end product metal complex compared to…

  • Phosphorus = Hesperus Summary

    and also it was an astronomical discovery 2. Statement 3 “Phosphorus = Hesperus” is a trivial statement that can be understood without any logic work at all. The two statements are particularly interesting because although statement one is referring to one object and statement two is referring two objects but in fact they are referring to the same identical object. What Frege was able to take away from this argument is that each singular term can have multiple understandings. Ferge proposed two…

  • Phosphorus Cycle Essay

    Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Biogeochemical cycling is defined as the chemical element flow between the living and nonliving components of the ecosystem. This is the cycle of nitrogen, phosphorus and carbon being converted into organic substances of plants and animals that are released back into the environment. There are three ways that human activities cause an imbalance of…
