Producing Chloride Using Nitrate and Sodium Chloride Purpose of activity The purpose of the activity was to produce the insoluble salt silver chloride using the soluble salts silver nitrate and sodium chloride which I prepared in unit 1 activity 2a AB + CD = AD + CB ================= silver nitrate + sodium chloride = silver chloride + sodium nitrate Portfolio Evidence – (Lukas Chamberlain) Activity 3.1-3c: Precipitation Safety Points Sodium Chloride · Wear safety
Silver chloride (Report) Silver chloride is an ionic chemical compound with the chemical formula, AgCl. Silver chloride has a electronegativity of 1.4 and is known be rather, extremely low with regards to water solubility. It has a density if 5.56 gm/cm3, a melting point of 455 degrees and a boiling point of 1,547 degrees and the state of this compound is solid in room temperature. When heated, AgCl converts to silver and chlorine, which is evident by the greyish or purplish prominence of the compound

halogen it if it forms a stronger bond with the carbon. In this investigation I will be examining the rate of reaction of chloroethane, bromoethane and iodoethane, by treating them with a solution of silver nitrate in a mixture of ethanol and water, and timing how long it takes for a silver halide precipitate to become visible. The faster the precipitate appears, the more reactive the halogenoalkane. Primary halogenoalkanes will be used, as they take longer to react than secondary
different half-cells will be prepared and connected to find the voltages generated. Also, the concentration will be change in one of the solutions to see how this affects the cell potential. Thirdly, the electrical potential of a cell containing silver and silver chloride will be measured. Lastly, a cell containing copper (II) and ammonia will be constructed. The potential and the Nernst equation will be used to calculate the formation constant of the tetraamminecopper (II) complex ion. This experiment uses
the most polished product of mankind. One of the earliest recorded standardized coins was made by the Roman Empire, consisting of gold, silver and bronze. Now in the modern age, coins are made with alloys (solids made up of a base metal and other elements), with the exception of bullion coins which are made up of precious metal (Gold, palladium, platinum and silver) and kept as a store of value or an investment, instead of day-to-day use.

imported from Italy where the guest would be ferried across the water by a gondolier to the hotel. The two hotels, Oklahoma Row and Missouri Row held the record for the longest log buildings in the world. Purchasing the 320 acre tracks of land that Silver Springs sat on, Coin built a summer resort. There were problems with Monte Ne from the beginning, some were self-imposed and some were outside of Coin’s control; a disagreement among the stockholders caused financial failure; reallocation of resources
Colloidal silver is a supplement that has been used for hundreds of years, dating back to the 19th century with French surgeon Dr. Carl Crede.1 Colloidal silver is a product that has little respect in the Food and Drug and Administration’s eyes but plenty of attraction in the natural and holistic medical field. The specific component of colloidal silver that my research is on is ACS 200, which stands for Advanced Cellular Silver. I have personally used ACS 200 before. I used the product to treat
part of the experiment and discussed in the results above, the confirmation of silver was justified since lead and silver each have distinct characteristics and unique responses that were expected to occur with each reagent. The observations that would have been made if lead was present, such as the critical formation of yellow precipitate when K2CrO4 was added, was negative. However, the results that were expected if silver was present were all justified with clear and evident results gathered throughout
of the unique pieces we see people wearing today steam from old cultural and ethnic roots. African and Asian influences are two prominent styles that often float in and out of popular culture and fashion as trends and style change. Usually found in silver jewelry, Celtic design is beautiful for its simple elegance. Basic lines come together to form elaborate designs. Celtic designs are also found in a lot of modern jewelry. While much of the Celtic jewelry today is often found in catalogues and stores
Have you ever wanted to know every fact about gold? Well today is your lucky day. The human body is composed of many different elements. Over 96% of our body weight is a combination of oxygen, carbon, hydrogen and nitrogen. While it's not the main ingredient, gold can also be found knocking around inside our cells. An average 70 kilogram human contains 0.229 milligrams of gold. gold is a transition metal. Transition metals are unique, because they can bond with other elements using not just their
are gold, platinum, silver and palladium bullion coins. To help in identifying the most suitable venture, here is an extensive evaluation of various bullions. Silver Silver is one of the most valuable precious metals due to its tangible and secure nature. One of the factors why you should purchase silver bullion over others is that the coins are small making them easy to store. In addition, they are cost-effective when considering adding them to investment portfolios. The silver bullion consists of
"We have this mentality that no one should be offended in any way. But the truth is..." Some may not understand what to take from this. For some it could create an idea of saying things that are offensive, simply because they are true. That is not what this line means. Everyone is offended by something. Offense is also one of many factors that can destroy relationships. The determining factor of offense is the choice we make as a result of the offense. "Everyone is offended by something." This
Heat Loss PROBLEM ======= I have been asked to investigate the link between colour and heat loss. Does the silver or the black cup lose its heat faster? HYPOTHESIS ========== I think that the black cup will lose heat faster than the silver cup because black absorbs heat, then releasing it out of the cup into the surrounding air and surface, where as the silver cup will reflect the heat back into the cup therefore keeping the water hotter for longer.

The Merchant of Venice is a romantic and funny play that has a lot of characters. In Shakespear times people found different things funny like insulting foreigners. There is always some form of drama in plays this makes the audience more excited and more into the play.One of the most dramatic plots in the play was when a wealthy heiress named Portia had to find a husband. Portia was a wealthy woman that inherited all her fathers money and her father left three caskets if someone wanted to marry
people were literally “autochthonous,” born from the soil, and partly from the stories of the philosopher Hesiod who chronicled the genealogy of the gods and goddesses as well as their accomplishments and exploits. Hesiod’s account of the Golden, Silver, and Bronze races which had succeeded one another before the current to “The Republic’s” age of Iron forms the basis for the myths of the metals. Since the ancient Greeks were convinced that all myths were primarily the work of even more ancient poets
common to describe a woman a beautiful. Especially when Mrs.Dickinson is a typical model of beauty. She is well fashioned in what she wears, she has real good dressings. "She was a gallant-looking woman, wearing to-day in London a coat and skirt, a silver fox, white gloves and a dark-blue toque put on exactly right".(P110) As a model of beauty, she is also very attractive on herself. "She was a charming woman walking by herself". (P112) Because she is such a good looking, lovely woman, there is no
In the poem 'To the Snake'; the author Denise Levertov use several writing techniques to portray money and gambling. She uses syntax, sound imagery, color imagery, figurative language, and symbolism to represent money and gambling. Symbolism is used cleverly throughout the poem to depict a number of things that would take numerous readings to see. Throughout the poem the sentences are structured so that every other sentence is indented, with exception to the first two and the last four. In those
Silver is a well known element in our everyday lives. Silver is used constantly in society in jewelry, silverware, currency, manufacturing, electricity and even occasionally medicine practices and studies. Similar to the multiple ways silver is used in our everyday lives, it was used commonly long ago. Archaeological evidence suggests that silver has been mined and collected for nearly five thousand years. The first accounts of silver being collected was in 3000 BCE. Back then, it was said silver
