Silver chloride

test, a few drops of Barium chloride was added followed by a few drops of HCl to a known compound. Formation of a milky white precipitate BaSO4 proves presence of sulfate ion. The same reaction was run again, only with the unknown. No precipitate formed, so sulfate is not present in the unknown compound. For the chloride test, HNO3 was added to the known compound, followed by AgNO3. A white precipitate of silver chloride is formed, confirming the positive result of chloride ion. When the test…

A. Heating Magnesium: This station consisted of magnesium, a slim, flexible, silver metal and a Bunsen burner. We used crucible tongs to hold the magnesium over the Bunsen burner until it began to ignite. When it first ignited, sparks were seen and the flame emitted a bright, white light. The flame spread across the magnesium and eventually turned it into a white, ashy substance. The combination of fire and magnesium caused a chemical change. This is evident as there were many signs of a…

Sediment-hosted copper deposits are formed by fluid mixing in permeable sedimentary and (more rarely) volcanic rocks. Two fluids are thought to be involved: an oxidized brine carrying copper as a chloride complex, and a reduced fluid that commonly formed in the presence of anaerobic sulfatereducing bacteria. For a sediment-hosted copper deposit to form, four conditions are required: (1) an oxidized source rock, (2) a brine to mobilize copper, (3) a reduced fluid to precipitate copper, and (4)…

exchange and produce two new compounds. In the reaction, Calcium and magnesium element of two compounds exchange, forming the calcium sulfate and magnesium chloride. I noticed that during the reaction, some white powder is produced and starts precipitating at the bottom of the test tube. After checking calcium sulfate and magnesium chloride in the solubility table, I found out that the precipitate is calcium sulfate as it is insoluble in water. In addition, double displacement also occurs in…

physical states and all of the reactants and products that are produced. Our first equation was the synthesis (composition) of magnesium reacting with oxygen and magnesium reacting with nitrogen. The magnesium began looking like a strip which was silver and smooth. Once lit it began to produce a vibrant white/yellow light that enveloped…

(Jefferson Lab Web). However, even though this element was found by Arfvedson, William Thomas Brande and Sir Humphrey Davy were the first people to isolate it (Jefferson Lab Web). Lithium is very abundant, it is a soft silver white alkali metal with the atomic number of three. Lithium is silver and contains no odor (Element Project). In addition to those features, lithium has a total of seven isotopes, two natural and five unnatural. The two natural occurring isotopes are 6Li (7.59%…

chemicals. His experiments with mercury vapor proved to be successful. However, the problem of light continuing to darken the silver plates on which the image was captured remained. Daguerre discovered that a regular table salt could stop the process. Later he learned that a hyposulphite of soda also called sodium thiosulphate could work even better. It washed the unexposed silver iodide protecting the image from darkening and eventually disappearing. He called his images…

precipitate formed, and therefore, from Figure 2, the anion is identified as Cl-. Most sliver compounds are insoluble, and when a soluble compound that contains Cl- reacts with AgNO3, an insoluble silver chloride precipitate forms.11 Since the cation is Na+ and the anion is Cl-, the unknown ionic compound is sodium chloride,…

History of Photography Although many may know what photography is, they do not know how far it has come from the beginning of its time. Photography, in itself, is one of the fastest growing hobbies in today’s world. Many believed it was “the killer of fine art” (Tolmachev) as it began to develop. The changes of photography and the people who have contributed to its advancement, have played a vital part in bringing it from its humble beginnings to its present day technological astonishment.…

instability of the complex in solution is due to cyanide ions moving in the solution. The movement of cyanide ions affects the central atom which is iron that stabilizes the complex. Potassium hexacyaferrate (III) reacts with silver and produces silver hexacyanoferrate.5 Silver hexacyanoferrate is used in photographic processes. Potassium hexacyanoferrate(III) reacts with other salts violently, for instance, sodium nitrite reacts with potassium hexacyanoferrate(III) where it oxidizes ammonia to…
