Magnesium sulfate

Of the most abundant elements together 98 percent of the 8 elements form the mass of the earth’s crust, ocean and atmosphere. Two of the most abundant elements of the eight are calcium and magnesium. Calcium and magnesium are located on the periodic table located both in group 2 sharing the same family meaning that they share chemical property’s as well as the same valence electron because of their location and family relation to the period table. The alkaline metals are a reactive group of…

lab. The purpose of this lab was to perform the Grignard reaction and to obtain the final product triphenylmethanol from a halide, phenylmagnesium bromide and the starting material, methyl benzoate along with the Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of the Grignard Reaction lab was to obtain the actual yield of…

This is a test to see if SO4 is present in the solution. If the mixture has a white precipitate of Barium Sulfate, then the solution has a sulphate ion present (4). Taking one of the remaining test tubes, add 0.1 mL of BaCl2 into the solution and mix well. HCl Test Fig 5. If HCl is present in the solution, bubbling and a strong smell of ammonium should be…

A detailed description of soil locations, textures and physio-chemical properties can be found in Sections 2.3.1(page 41) and 3.3.1(page 56). We selected four types of soils out of seven types of soils, namely MGA, KBA, TAA and DUA. Key soil characterisation of these four soils is summarised in Table 4.2. The reason why these four types of soils were chosen for this chapter was that they had distinct soil parameters in terms of total organic carbon (TOC), Fe oxide, Al oxide, pH which have been…

1. Observation. - Compound X is a white powder. It is a solid. 2. Questions. - What is compound X? - What will happen when compound X is heated and reacted with C20H14O4 (phenolphthalein – an acid-base indicator)? (1) - How does compound X react with C20H14O4 (phenolphthalein)? (2) - How does compound X react with water? (3) - How does compound X react with hydro chloric acid (HCL)? (4) 3. Predictions. - Compound X is calcium carbonate (CaCO3). - (1) When compound X is heated and reacted with…

In order to obtain that result through calculations, the water vapor pressure and the water height correction had to take place. After, the combined gas law had to be utilized and manipulated to find the volume and divide that volume by moles of magnesium. Being close to the theoretical value, 22.4L, it verifies that one mole of all gases occupy 22.4L in any container under standard temperature and pressure. This information could be valuable in many ways. For example, it proves Avogadro’s Law…

course of the experiment, the results were not expected. At the beginning of the experiment all reagents produced satisfactory results, the reactant 2-bromopropane was determined to be the limiting reagent for the Grignard formation and the Isopropyl Magnesium Bromide was correctly formed. However, random errors occurred at the nucleophilic addition step. At this period, it was observed there was not condensation happening inside the reflux condenser while the mixture was being heating, and as a…

Magnesium is one of the most important minerals for human health and is required throughout the body; but by far the largest quantities are found in the bones and muscles. Almost all the body's enzymes are dependent to some degree on adequate supplies of magnesium, and these enzymes are essential for several hundred vital metabolic reactions; amongst the most important being the production of energy within cells through the metabolism of dietary proteins, carbohydrates and fats. Magnesium is…

where mCO2 is the mass fraction of CO2 in the solution, and MWsolution, MWbrine, and MWCO2 are the molecular weight of the solution, of the brine, and of CO2, respectively. Considering the definition of density as shown on 5.5, equation 5.3 can be modified to equation 5.6. ρ_CO2=MW_CO2/V_CO2 (5.5) "1" /"ρ" _" solution" =("1-" "m" _"CO2" )/"ρ" _" brine" "+" "m" _"CO2" /〖"ρ" _"CO2" 〗_" " (5.6) where ρ solution and ρ brine are density of solution and brine, MW CO2 and ρm CO2 is…
