  • Solid Solubility Lab Report

    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 conduct thus allow electrons to freely move within the solid thus create a flow of electron current. Conclusion, they are mechanically similar because both create a flow of particles (ions, free electrons) that enable the flow of electrons current within…

  • Solid Phase Synthesis Essay

    A novel solid-phase synthesis methodology of N-substituted-2-aminothiazolo[4,5-b]pyrazine derivatives was developed. The key step in this synthesis strategy is tandem reaction of isothiocyanate terminated resin 2 with o-halo-2-aminopyrazine, affording cyclized 2-aminothiazolo[4,5-b]pyrazine resin 4. To increase the diversity of our library, Suzuki coupling reaction was performed at the position C6. Further functionalization of 2-aminothiazolo[4,5-b]pyrazine core skeleton with various…

  • The Melting Point Of Urea And Trans-Cinnamic Acids

    The melting point of a substance is best described as the temperature at which a solid becomes a liquid (Bruice 2014). On the molecular level, when a compound melts the forces between the molecules become weaker. This is because when a substances heats up the kinetic energy between the molecules increase causing the molecules to vibrate. When the vibrations become strong enough for the molecules to move around and pass other molecules, the compound that is being heated up starts to melt and…

  • Flask Synthesis Lab Report

    During the extraction process, the sand bath was set to 20℃. The 1.00 gram of ground nutmeg was transferred to the round-bottom flask (RBF) using the plastic funnel. Three milliliter of tert-butyl methyl ether and two or three boiling chips were added into the flask. The black plastic connector was used just like the distillation column with air condenser set-up. The flask was clamped to the ring stand using 3-pronged clamp. The flask was lowered into a slightly depression in the sand without…

  • Double Salt Lab Report

    the salt, it dissolved relatively quickly with the help of a glass stirring rod. As they dissolved the solution, it turned to a clear light blue color similar to that of the sky. The hydrochloric acid did not visibly change the appearance of the solution. Once stirred, they, lit the Bunsen burner and heated the solution until it was almost boiling, all with the stirring rod still inside the beaker. Then experimenters added 15 mL BaCl2 into the 250-mL beaker all at once, at which point the…

  • Recrystallization Essay

    The main purpose of this experiment is to purify an impure solid by the technique of recrystallization. This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent…

  • Fepo4 Temperature

    Paragraph 1 The research done by Haines on how the atomic structure of FePO4 varies when temperature increases from 294K to 1073 shows few crystal chemical relationships between SiO2 and FePO4. There is a first order variation of cell parameters and atomic orientations with temperatures lower than 980K and α-phase plays a dominant role over β-phase at high temperature. For the α-phase FePO4, the cell parameters increase with a non-linear trend when temperature increases linearly. The volume…

  • Acid Base Or Neutral Essay

    ethyl-4-aminobenzoate, and acetanilide, two of them were randomly given out, weighing 75 mg each. These mysterious substances were both placed in a 25-mL flask with 6 mL of diethyl ether. The substances with the diethyl ether were mixed together until the solids dissolved. The solution was cooled in an ice bath for a couple of minutes. Once the solution was cooled, 3 mL of 3M HCl was added and swirled into the solution. The top of the 25-mL flask was capped and the two liquid were mixed in a…

  • Toluene Solubility

    1) Important solubility characteristics for a solvent to be used in the crystallization of an organic solid that’s contaminated with impurities is that the organic solid should have low solubility at low temperatures in the solvent, but highly soluble at high temperatures. Also, the solvent should allow the impurities to be either completely soluble or completely insoluble at all temperatures. 2) One way to improve our percent recovery is by making a second crop of crystals by removing the…

  • Lab Report: Redox Chemical Reactions

    teal color after several minutes. Later, reaction ten turned into a green solution first, then a yellow-brown, to finally a brown/mustard color. It contained a precipitate in the solution and it was almost like a “pea soup” green when it was fully reacted with the two reactants. Part III started with reaction eleven that created bubbles, smoke, and it was fizzing while turning completely white when it reacted. The solid, when dissolved, also created an evolution of foaming gas. The physical…
