Corrosion inhibitor

Frame: The purpose of this lab is to determine if the iron given in the experiment is Fe (II) or Fe (III). Knowing what chemicals are present in a reaction and what chemicals are produced is significant information that can be applied to real world situations. An example of this is rust. Rust usually occurs when iron reacts with water. By being aware of this, substances can be made to remove unwanted rust. The mass of the collected samples will decrease as it is dried due to evaporation. Excess…

The purpose of this report and lab was to assist in visualizing the structure of infinitesimally small objects and how they fit together. Normal object fit together similarly to microscopic atoms and experiment 2 exploits this to help understand structure property relationships. The knowledge gained here directly applies to the world as applications of the materials becomes apparent as the properties are explored. Copper There are a plethora of modern technological uses of copper. It can be…

Corrosion is when metals or other materials corrode over time. “Corrosion is a two-step process that requires three things: a metallic surface, an electrolyte, and oxygen. During the corrosion process, surface-level metal atoms dissolve into an aqueous solution, leaving the metal with an excess of negative charge.”(Corrosion, Boundless Chemistry, First two bullet points) The nail will undergo a corrosion process as it is placed in the cup filled with salt water. However, depending on the coating…

What Is Slate Shingle Metal Roofing And Why Is It Better Than Slate Stone Tiles? Slate shingle metal roofing is a roofing material made from metal and stamped to mimic the appearance of natural slate stone. A slate stone roof adds a touch of luxury to your home, but there are a few reasons why the metal version is superior. If you love the look of slate, you may want to look into slate shingle metal roofing. Here are a few reasons why. Metal Slate Tiles Are Much Lighter Than Stone One reason…

Fig. 2 and Table 1 present the open circuit potential versus time curves and self-corrosion rate of Al, Alloy 1 and Alloy 2 electrodes in 2 M NaCl electrolyte, respectively. Corrosion rates were obtained by weight loss measurements in 2 M NaCl solution after 60 min. As seen in Table 1, the corrosion rate increases in the following order: Al ＜Alloy 1 ＜ Alloy 2. Fig. 2 indicates that open circuit potential of Alloy 1, 2 (especially Alloy2) is more negative than that of Al. It can be seen that the…

Question 1 Part A: General Topic Properties of stainless steel • Corrosion resistant • Good tensile strength • Good low and high temperature service • Appearance • Hygienic • Has a respectable friction coefficient Corrosion resistant Stainless steel has a chromium-rich rust protective oxide thin film on the surface known as a passive layer, in which prevents corrosion by blocking oxygen diffusion to enter the passive layer and spreads rust into the internal material. As seen in Figure 1,…

Kettlebells may seem to be a new popular trend amongst fitness enthusiasts and athletes, but the truth is that they have been around for centuries with ancient findings of their use for dynamic strength and endurance training. Nobody can quite figure out their true origins, and only theories have been made for what the kettlebell was actually created for. However, records in archeology actually show that they existed as far back as ancient Greece. Proof of these records can be found in Athens,…

The Farberware 6-Quart Digital Pressure Cooker has both pros and cons for me. My family received it as a gift so I do not know if it is worth its price, but I do know whether or not it is worth getting based on how useful it may or not be based on your individual needs. First, I will mention the pros of this pressure cooker. I like pressure cookers because you can just set them aside and let it make the dinner for you. This one is no exception, it acts like most pressure cookers. You can fill…

1.5 Drugs targeting the Rab prenylation pathway 1.5.1 Prenylation pathway Prenylation of Rab proteins is the essential lipid modification step that begins the membrane trafficking cycle. It is a crucial post-translational modification that allows the stable attachment of Rab proteins to the membrane by increasing hydrophobicity to be able to insert into the lipid bilayer (Maltese, Wilson and Erdman, 1996). As depicted in Figure 7, the Rab cycle starts with a Rab protein that is GDP bound, in…

insufficient communication is an inhibitor to collaboration in online classes. The idea that insufficient communication is not an inhibitor to collaboration is not supported by Tetard, Patokorpi & Packalen (2009) who found that problems with including collaboration in online courses included the need for effective communication support in the course management system. While there was not a high level of survey participant agreement with insufficient communication as an inhibitor to collaboration…
