INTRODUCTION
Ferrate is a supercharged iron atom in which iron is in the in addition to 6 oxidation state; it is otherwise called Iron(VI). Ferrate is greatly effective, can convey numerous medications from a solitary application, does not make purification side effects, is earth well disposed, and explains troublesome treatment challenges that different oxidants can't touch. In particular, Ferrate is frequently the minimum lavish and best treatment alternative.
Ferrate(VI) is the inorganic anion with the synthetic equation [FeO4]2−. It is photosensitive, contributes a pale violet shading to mixes and arrangements containing it and is one of the strongest water-stable oxidizing species known. Despite the fact that it is delegated a powerless

Additionally, the ferric oxide produced from ferrate(VI) acts as an effective coagulant that is suitable for the removal of metals, non-metals, radionuclides, and humic acids (Sharma 2002, Sharma et al. 2005b).
METHODOLOGY
• Preparation of Sodium Ferrate(IV)
Sodium ferrate(IV) was arranged by the system depicted by Scholder and Bunsen (18). Twenty-four sections of Fe203 and 40 sections of Na20 (K & K Laboratories, Plainview, N.Y.) by weight were personally blended in a porcelain mortar without HO and CO (in a powder box free of CO and HO). The mixture was exchanged to an unmanageable watercraft (sintered corundum) and set in a tubular heater at 150°C through which dry oxygen streamed. In the following 30 minutes the temperature was expanded to 450°C and yielded sodium ferrate(IV) following 60 minutes.

The technique calls for about quantitative yields, however our planning contained on the normal just fifty percent sodium ferrate(lV). The error is credited to the vicinity of little amounts of dampness in the materials and mechanical assembly. Sodium ferrate(lV) disproportionates in water or basic arrangements as per the response:
4 + 8H 0—>Na2 Fe04 + 2Fe(0H)3 +
The purpose for this lab was to use aluminum from a soda can to form a chemical compound known as hydrated potassium aluminum sulfate. In the lab aluminum waste were dissolved in KOH or potassium sulfide to form a complex alum. The solution was then filtered through gravity filtration to remove any solid material. 25 mLs of sulfuric acid was then added while gently boiling the solution resulting in crystals forming after cooling in an ice bath. The product was then collected and filter through vacuum filtration. Lastly, crystals were collected and weighed on a scale.
During our investigation we first decided how much sodium bicarbonate we would be using. We decided on 11 grams which was about half of the crucible. We then used the bunsen burner to heat up the sodium bicarbonate. We heated the sodium bicarbonate expecting there to would be a chemical reaction and the atoms would be rearranged during thermal decomposition. We heated the sodium
This paper describes the methods used in the identification, investigation of properties, and synthesis of an unknown compound. The compound was identified as calcium nitrate by a variety of tests. When the compound was received, it was already known to be one of twelve possible ionic compounds. The flame test identified the presence of the calcium anion in the compound. The compound tested positive for the nitrate cation using the iron sulfate test. At this point it was hypothesized that the compound was calcium nitrate. Reactivity tests and quantitative analysis comparing the unknown compound with calcium nitrate supported this hypothesis. Synthesis reactions were then carried out and analyzed.
In our experiment we utilized the hydrate cobaltous chloride. Hydrates are crystalline compounds in which one or more molecules of water are combined with each unit of a salt. Cobalt (II) chloride hexahydrate is an inorganic compound which is a deep rose color in its hydrated form. As an inducer of
We thank the University of Oklahoma and the chemistry faculty for providing the space, instructions, and equipment for the development of this report and experiment.
The oxalic acid dehydrate solution was titrated using NaOH solution until light pink color can be seen. (does not disappear when the solution was mixed).
In conclusion, both feldspar and olivine are chemically separated in industrial scales. Feldspar by the method of flotation that takes advantage of the hydrophilic and hydrophobic properties of minerals, and olivine by the method of thermal separation that takes advantage of the melting point of olivine and other materials.
In the demo experiment, we placed 10 grams of Ammonium dichromate in the form of a solid before starting the experiment. When the experiment begins the Ammonium dichromate is burned up and then produces Chromium (III) oxide as a solid, Nitrogen gas and water in form of a gas. In the experiment, we combined Zinc Chloride and Sodium Sulfide in which both chemicals are aqueous. The result of the combination was Zinc Sulfide a solid and Sodium Chloride an aqueous solution. In the alternate experiment, we combined Lead (II) Nitrate and Potassium Iodide in which both chemicals are aqueous. The result of the combination was Lead (II) Iodide and Potassium Nitrate.

The purpose of this experiment was to find the physical and chemical properties of many different substances. The physical and chemical properties of: Sulfur (S), Iron fillings (Fe), Sodium bicarbonate (NaHCO3), Sucrose (C12H22O11), Sand (SiO2), Magnesium (Mg) and Sodium chloride (NaCl) were all recored. While observations where made about: Iron fillings mixed with Sulfur with and without a magnet, Magnesium both burnt and unburnt, Magnesium (ash and unburnt) mixed with Hydrochloric acid, Sodium bicarbonate with Hydrochloric acid, burned Sucrose and its solubility, Sodium chloride mixed with sand and

Ferrous sulfate is an essential body mineral; a type of iron. The effect pursued is to prevent and/or treat iron-deficiency anemia. Dosage: Taken orally - one tablet a day in the morning. Mrs. H has been taking it for 10 years and stated suffering of occasional constipation. No adverse effects reported.
The procedure for this experiment can be found in Inorganic Chemistry Lab Manual prepared by Dr. Virgil Payne.
This experiment consists of titrating the ferrous ion with permanganate ion to study the oxidation-reduction reaction. The ions react in acidic solution to give ferric ion and a reduced ionic form of manganese. All the reactants and products except permanganate ion are weakly colored, whereas permanganate is a very intensely colored ion. Then a solution of permanganate is removed as long as there is a ferrous ion present to react with it. But as soon as the entire ferrous ion has been oxidized, the next small portion of added permanganate colors the solution. The first appearance of a permanent pink color indicates the endpoint of the experiment. From the titration it will be able to calculate the percentage of iron in the sample from the data.
