Crystallization

Candy is made in variety ways and they are made in scientific method such as by boiling, cooling down and crystallizing. To make candies you always start with dissolving sugar in the boiling water so that sugar will change to sugar syrup. To begin with, the article mentions that if you want to make rock candy, you need to let the syrup cool down for long time so that it will change into big sugar crystals. However, if you want to produce fudge, you need to continuously stir the syrup after…

Thiamine hydrochloride is structurally similar to thiamine pyrophosphate (TPP). TPP is a coenzyme universally present in all living systems. It catalyzes several biochemical reactions in natural systems. It was originally discovered as a required nutritional factor (vitamin) in humans by its link with the disease beriberi. Beriberi is a disease of peripheral nervous system caused by a deficiency of Vitamin B in the diet. Symptoms include pain and paralysis of extremities, emaciation, and…

The objective for this lab is to construct a solubility curve for potassium nitrate in water by measuring saturation temperatures for six different solution concentrations. We form a group of four and were assigned to work on series one while the other group work on series two. Throughout the lab, we set a hot bath water temperature at 85 degree celsius which affected how potassium nitrate dissolves in water and changed the saturation temperature. In addition, our group discovered that the mass…

brief summary of your experiment. The experiment was conducted by creating a K3Fe(C2O4)33H2O solution using DI water, 3.501 g of iron (II) ammonium sulfate, H2C2O, K2C2O4, and H2O2. 5 ml of ethanol was dispensed within the solution to aid in the crystallization of the oxalate. The results of the experiment did not provided crystals of the oxalate rather crystals of impurities formed within the solution with 5 mL. 2. Write the balanced chemical equation for each step in which you observed a…

A mineral is defined by geologists as naturally occurring, generally inorganic, solid substances, with an orderly crystalline structure, and a definite chemical composition that allows for some variation. The following are examples of materials and whether or not they fit the definition of a mineral. Window glass is a non-crystalline solid that is synthetically created from silica, generally used for its optical transparency. Glass is an inorganic solid with a definite chemical composition.…

Russell Stover’s all milk chocolates have a wide variety of ingredients. The main ingredients needed to make the product are milk, sugar, chocolate, cocoa butter, and soy lecithin. The chocolate and cocoa butter come from the cocoa bean. The cocoa bean comes from a cocoa tree and is grown by farmers around the equator (Barry Callebaut). After the beans are fermented and dry enough the cocoa farmers will bring them to collection centers or cocoa plantations (Barry Callebaut). Next the beans…

results in three distinct bromo-nitrobenzene products: ortho, para, and meta. The ortho and para forms of the product are more stable than the meta form. The two stable forms need to be separated from each other, which is done through fractional crystallization and leaves the para form in solid form since it is less soluble in polar…

In relation to real estate, 'security' is understood to be the process of taking necessary actions to ensure that one's property is safe and is not susceptible to attacks from outsiders, unlawful entry and robbery. Due to the critical and essential nature of security of property, it has become a profitable business. Some aspects that determine the kind of security system chosen are that of the expenses involved, the type of building (housing or business related) and the dependability of the…

The objective of this lab was to brominate a hydrocarbon by converting 2,3-dimethyl butane to 2,3-dibromo-2,3-dimethyl-butane through crystallization. In order to verify the purity and the identity of the product two tests were done, one was using melting point and the other was NMR. The melting point range found in this test was between 138°C-175°C, whereas the ideal melting point for the product was 168°C. Based off of the melting point range, it can be assumed that the product had formed…

11/4/2017 Original Synthesis of Cadmium Nitrate Tetra-Hydrate Cadmium nitrate tetra-Hydrate is an inorganic compound from the family of compounds with the general formula Cd (NO3)2.XH20, where X=4, hence the molecule has four molecules of water of crystallization in its structure. It exists as a salt but in its anhydrous state, it is known to be a volatile substance. It is a colorless substance as are all the compounds in the family of cadmium nitrates. Cadmium nitrate is a colorless,…
