Silver chloride

a large surface area that can amplify the intensity of chemical properties. For AgNPs, the antibacterial abilities of silver tend to promote more intense interactions with the surrounding micro- and macro-organisms12. When the AgNP is oxidized by surrounding conditions such as temperature, chemical interactions or pH, the nanoparticle becomes a trojan horse by releasing silver ions13, 19. However, AgNPs may be altered to have stabilizing surface coatings that help stabilize the nanoparticles…

hydrogen atoms have a positive pole. The polarity of water makes it unique and allows it to perform as a solvent (Duke University, n.d.). Since water is a solvent, most material found in saltwater is dissolved. The most present ions are: sodium, chloride, bromine, and different…

and light the paper with a match. Observe and record reactions. Deposit a microspatula of NaCL (sodium chloride) into a test tube, and dilute the substance by infiltrating approximately an inch of water to the test tube. Let the NaCL dissolve into the water by shaking the test tube with one’s thumb over the opening of the test tube. Using a dropper, place three drops of 0.1 M AgNO3 (silver nitrate) to the NaCL-water concoction. Document findings. With scissors, cut a 2 cm magnesium ribbon in…

with a small hole in one side. The light from the scene passes throught this single point projects an invertied image on the other side of the box. Shortly after they created the pinhole camera Albertus Magnus discovered silver nitrate, and George Fabricius discovered silver chloride.…

other types of illustration. Niepce’s interest then shifted and he began to experiment with ways to produce an image through the action of light upon photosensitive materials. He used paper that was made light sensitive through the application of silver chloride solution. Then, he would expose the photosensitive paper in a camera obscura. At first he experienced the same difficulties both Wedgewood and Davy faced; the image was too indistinct and the action of the light could not be thoroughly…

Potassium sulphate is often used in fertilizers to supply potassium. On advantage potassium sulphate has over potassium chloride is that I has a pH closer to neutral and therefore will have less impact on the pH of the soil. Potassium sulphate is also preferred as it provides a large amount of energy for the cost, 100% is usable by the plant. It is also needed in smaller quantities…

Once upon a time, Strontium, an element on the periodic table, was also nicknamed Sr. Her parents, strontium chloride and mercuric oxide, helped find her in 1808, she was a happy solid at room temperature. She was a huge elephant metal, weighing 87.62 grams. However she had one flaw like Brynn, she was as ugly as a spoiled egg yolk that’s been left outside for five days. This unfortunate appearance placed her 38 on the periodic table and made her upset like an Eeyore on Winnie the Pooh. Many…

Chemistry Honors Mrs. Moreno Period 5 INTERPRETING THE PERIODIC TABLE Partner’s name: Faranak Hajikhan, Pablo Moncada, Albina Contreras and Karla Santos Title: Interpreting the Periodic Table Date: 12-18-14 Subject: Honors Chemistry / Period 5 Introduction: The periodic table is a table of the chemical elements in which the elements are arranged by order of a atomic number. The periodic table also has a special name for its vertical columns. Each…

Atomic structure AC1.1 1. Produce a table showing each sub-atomic particle with their relative masses and charges (Bbc.co.uk 2015). Particle Relative Charge Relative Mass Proton +1 1 Neutron 0 1 Electron -1 2. Explain the meaning of the terms, ATOMIC NUMBER and MASS NUMBER of an atom in terms of sub atomic particles. The atomic number refers to the number of protons in an atom, the mass number refers to the number of protons plus the number of neutrons (Bbc.co.uk 2015). 3. A…

daguerreotype process, allowing people to actually obtain permanent images by camera. Daguerre's process somehow “fixed” the images onto a sheet of silver-plated copper. He polished the silver and coated it in iodine. Then, he put the plate in a camera and exposed it to light. After the image was painted by light, Daguerre covered the plate in a solution of silver chloride. The process created a lasting image unlike past inventors where their images took long to develop and would quickly…
