Magnesium hydroxide

(Maximum length 1 page including chemicals equations) The hypothesis of this experiment is that empirical formula is going to be close to a ratio as 1:1, because that is the theoretical empirical formula for the compound magnesium oxide. Empirical formula is simplest formula for a compound, it is the smallest possible whole- number ratio of subscripts of the elements in the formula. Generally, this the same thing as its simplest molecular formula, this is generally the actual number…

3.2 Mechanochemical synthesis The mechanochemical method was employed to synthesis CP and MgCP where calcium hydroxide (CaOH2), phosphoric acid (H3PO4) and magnesium hydroxide (MgOH2) were used as precursors. Table 3.1 shows the parameter used by varying the weight percentages (wt. %) of Mg. Table 3.1: The weight percentages ratio for magnesium doped calcium phosphate Samples Parameter Calcium Hydroxide Ca(OH)2 (g) Phosphoric Acid H2PH03 (g) Magnesium Hydroxide Mg(OH)2 (g) Undoped CP…

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…

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 which states that at a standard temperature and pressure, one mole of any gas will occupy the same value which is 22.4L. Like a puzzle piece, once discovered, it…

A. Heating Magnesium: This station consisted of magnesium, a slim, flexible, silver metal and a Bunsen burner. We used crucible tongs to hold the magnesium over the Bunsen burner until it began to ignite. When it first ignited, sparks were seen and the flame emitted a bright, white light. The flame spread across the magnesium and eventually turned it into a white, ashy substance. The combination of fire and magnesium caused a chemical change. This is evident as there were many signs of a…

The results obtained for this lab were very unsatisfactory, even though the results sustain a general trend throughout the 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…

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…

This lab was a two week long lab called the Grignard Reaction 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…
