Total dissolved solids

VII. Discussion 1. Why was the solution heated and then cooled during the recrystallization of the crude acetaminophen? Recrystallization is a very important method of purification for organic solids. This process is carried out by the separation of compounds based on the difference in solubility. The steps to recrystallization can be described by the following • Choose an appropriate solvent based on the compound’s characteristics • Dissolve the compound in the minimum amount of solvent •…

Morgan Roberts Mrs. Freeman Honors Chemistry May 18, 2017 What Was the Effect of the Type of Dairy Product Used on the Height of the Ice Cream Formation? Purpose: The purpose of the experiment conducted was to find out how different dairy products used to make ice cream affect how tall of a formation can be shaped out of the ice cream. Background Information: Most people experience the joy of making their own ice cream when they are kids, but what is the science behind it? Homemade ice…

Table 3 shows the BET surface area of both the fresh and hydrothermally aged SCR catalysts. For fresh BEA zeolite and SCR catalysts, as the doping amount of catalytic additive increases, the BET surface area decreases, probably because the additive Cu, Ce, and Nb species blocked some of the zeolite channel, hindering the entry of N2 into the pores (Bin et al. 2014). After aging at 600 °C, all the samples showed 3-20 m2/g increased BET surface area. Aging condition of 600 °C is a relatively mild…

associated with removal of EDTA and nitrate/organic compounds [39]. The carbon and water molecules present on the sample evidence in FTIR spectra Fig. 2. In the third stage (400-1100°C) weight loss is 12% due to the dehydroxylation of HA [40]. The total weight loss of all the samples found to be 30-39%. However, there was no significant weight loss observed above 700°C, indicating that the synthesized samples are high thermal stability after heat treatment at above…

Paragraph 1 Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. Haines’ research paper studies the change that occurs in the FePO4 structure as it is studied from temperatures 294K to 1073K. A transition is noticed at 980K, when it’s tetrahedral α-quartz structure experiences high pressure levels, changing the structure to β-phase, a more dense octahedral structure. Cell parameters of FePO4 in α-phase increases in cell parameters and volume as…

A filter is something that removes impurities or solid particles from a liquid or gas that passes through it. There has been a total of 76% of deaths due to infections from dirty liquids and poisonous gases. Not many filters do the same job you would like it to do, but with this particular filter it is made to filter out gases, liquids, and solids from a variety of different elements and objects as well as cleaning any object you toss into it. The item's frame is powerful enough to do these…

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. Window glass…

Does rock salt effect ice? Rock salt effects the boiling and freezing point of ice. Salt has always helped the roads when it is icy in the winter, but a new idea for the roads may be the use of beet juice. In group A with the little bit of ice and water, that we continued to stir, the temperature decreased from 2°C to .5°C in five minutes. In group B, 10 grams of rock salt was added to the ice water and stirred. The temperature of the mixture decreased from -1°C to -6°C in five minutes. After…

In this experiment one, are determining the melting points of different crystalline substances following a specific procedure. By finding the melting point of a crystalline substance, it helps determine what kind of compound it is as well as initiate the purity. A DigiMelt apparatus can be used to determine the melting point where a small amount of the the substance is packed into a capillary tube and heated slowly in the apparatus which includes a thermometer, a heating coil and a magnifying…

Solid solubility is whether that solid can dissolve in specific solvent or not. When a solid dissolve, the ions that comprise the solid will disperse in the solvent thus create a different concentration distribution within the solvent solution. Thus we can view this as a flow of ion from high concentration to low concentration (there’s a flow of ions) Electrical activity is the ability for electron to travel within the material. Specific solid material molecule will have free electrons to…
