Copper (ii) sulfate, also known as cupric sulfate or copper sulphate, is the inorganic compound with the chemical formula cuso4. This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous salt is a white powder in its pure form, whereas the pentahydrate (cuso4â·5h2o), the most commonly encountered salt, is bright blue. Copper (ii) sulfate exothermically dissolves in water to give the aquo complex [cu(h2o)6]2+, which has octahedral molecular geometry and is paramagnetic. Other names for copper(ii) sulfate are "blue vitriol" and "bluestone"
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate, such as limestone. Calcium oxide is usually made by the thermal decomposition of materials such as limestone, that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 °C (1,517 °F), a process called calcination or lime-burning, to liberate a molecule of carbon dioxide (CO2); leaving quicklime. The quicklime is not stable and, when cooled, will spontaneously react with CO2 from the air until, after enough time, it is completely converted back to calcium carbonate Uses quick lime Quicklime is relatively inexpensive. Both it and a chemical derivative (calcium hydroxide) are important commodity chemicals. Quicklime produces heat energy by the formation of the hydrate, calcium hydroxide, by the following equation:[3] CaO (s) + H2O (l) Ca (OH) 2 (aq) (ΔHr = −63.7 kJ/mol of CaO) As it hydrates, an exothermic reaction results and the solid puffs up. The hydrate can be reconverted to quicklime by removing the water by heating it to redness to reverse the hydration reaction. One litre of water combines with approximately 3.1 kilograms (6.8 lb) of quicklime to give calcium hydroxide plus 3.54 MJ of energy. This process can be used to provide a convenient portable source of heat, as for on-the-spot food warming in a self-heating can. When quicklime is heated to 2,400 °C (4,350 °F), it emits an intense glow. This form of illumination is known as a limelight, and was used broadly in theatrical productions prior to the invention of electric lighting. Calcium oxide is also a key ingredient for the process of making cement.
Iron(III) chloride, also called ferric chloride, is an industrial scale commodity chemical compound, with the formula FeCl3 and with iron in the +3 oxidation state. The colour of iron(III) chloride crystals depends on the viewing angle: by reflected light the crystals appear dark green, but by transmitted light they appear purple-red. Anhydrous iron(III) chloride is deliquescent, forming hydrated hydrogen chloride mists in moist air. It is rarely observed in its natural form, the mineral molysite, known mainly from some fumaroles. When dissolved in water, iron(III) chloride undergoes hydrolysis and gives off heat in an exothermic reaction. The resulting brown, acidic, and corrosive solution is used as a flocculant in sewage treatment and drinking water production, and as an etchant for copper-based metals in printed circuit boards. Anhydrous iron(III) chloride is a fairly strong Lewis acid, and it is used as a catalyst in organic synthesis.
The compound Sodium chlorate is an inorganic material with the standard equation NaClO3. Its physical properties include being white in color and having a crystalline nature that promptly dissolves in water. It has been known to be hygroscopic (absorbing moisture from the air) in nature. It decays over 573 Kelvin to discharge O2 and leave behind NaCl. Quite a lot of Sodium chlorate is created every year, mostly for various uses in the oxidizing mash to deliver a high-quality paper. The physical properties of sodium chlorate are quite similar to other inorganic salts. Some of them are listed below- 1). It is an odourless compound. 2). Its color differs from light yellow to white crystalline solid. 3). It is very soluble in water and heavier than water. Hence, it can sink and break up at a fast rate. 4). While it is not an explosive by itself, yet it can cause powerful combustion on coming in contact with water. It causes a highly exothermic reaction. Even if 30% of molecules are in the water, they can cause a powerful oxidizing reaction due to their inherent properties. 5). Its density is 2.49 g/cm. 6). Sodium chlorates boiling point is 300 degrees C and the melting point is 248 degrees C. 7). It is also soluble in some organic solvents like glycerol and methanol. It is also slightly soluble in acetone. 8). It has a cubic crystal structure.
