Overall this experiment was successful, as it was possible to determine which unknown salt solution the cation belonged too, and also the pairing anion. To figure out the cations, many tests and observations were needed to be made. With the gathered flame test results, and the information given in the procedure, conclusions could be made. Solution A is Sr2+ since it tested crimson red. Solution C is Ba2+ because it tested green. Solution D is Li+ because it turned the flame carmine red. Finally,

the presence of water and that impurities may be still present in the product that was formed. Solid substances that contain soluble impurities typically melts at a lower temperature than the pure compound (Kirsop. 2017). This is because the impurity disrupts the repeating pattern of forces that holds crystalline structure of the solid. A smaller amount of energy is required to melt the part of the solid surrounding the impurity, which supports that the compound that was produced was an impure compound

Co-crystallization involves two main steps: nucleation (the material starts its crystallization process on a specific site) which can occur in labile zone that is a zone not optimal for crystal growth, and second the crystal or co-crystal growth. The solid crystals can be formed from liquid, melt or gas, and are more stable than the individual initial materials and held together by non-covalent forces. Compared to the initial material, the co-crystal has a different crystallinity, solubility and mechanical

Experiment #1: Purification of a Solid: Crystallization and Melting Point: Joseph Katz and Melissa Colwell Binghamton University, Department of Chemistry, Binghamton, New York 13902 Introduction: One of the most important parts of this experiment was the concept of the melting point. The melting point is the temperature at which a substance turns from a solid into a liquid. Every substance has a specific temperature

solution).Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs.Usually,the crystalline solid have highly ordered three dimensional arrangement of particles. Crystallization can be divided into two processes, nucleation and crystal growth. Nucleation is the initiation of a phase change in a small region, such as the formation of a solid crystal from a liquid solution.It is a process

The appearance is stated to be monoclinic crystals. When the substances melted completed, it went from solids to liquids.In Part 1, the melting point range of Urea was 132.5-133.5°C. It had a precise melting point in comparison to the given melting points. The melting point range of Trans-Cinnamic Acid had a melting range of 132.5-133.6°C. The Trans-Cinnamic

Include an image of one such compond. VOC's stand for "Volatile Organic Compounds" and are carbon-based chemicals. These compounds include hydrocarbons, partially oxidized hydrocarbons, and organic compounds. They are emitted as gases from specifc solids and liquids. VOC's are used in a number of household and industry products, for examplle; fuels (propane/gasoline), paint thinners, pesticides, cleaning supplies, correction fluids, permanent markers, etc. We are exposed to VOC emissions in our every

Introduction The process Sublimation is a method used to disconnect a -natural product from different undesired compounds and after that it is purified by the change of state from solid to vapor. The majority substances, under typical states claiming climate pressure, progress its stage with a temperature rise from solid to liquid and to gas. Meantime other compounds, like iodine and carbon dioxide experiences sublimation at this pressure. By bringing down the temperature and pressure of a system
