A silver-copper alloy had a mass of 0.1264 g. When the alloy was dissolved in nitric acid and the silver precipitated as silver chloride, the precipitate had a mass of 0.1375 g. Calculate the The purpose of the lab is to determine the percentage of silver in a silver alloy. In this case, the silver alloy is a dime. To determine the percentage of silver in the dime, we must separate the silver in the dime from the copper and other crud that is in the dime and find its mass. Analysis of Silver in an Alloy Pre-Lab Questions: (complete in lab notebook) 1. Define precipitate, soluble, and insoluble. 2. What is the difference between qualitative and quantitative analytical methods? 3. Why is it possible to analyze the silver content of a silver-copper alloy by precipitating with chloride ion? 4. The purpose of this lab was to calculate the percent of silver in an alloy using gravimetric analysis. Through the procedure mentioned in this report, the percent of silver in an alloy of a U.S. Mint dime made before 1965 was 90.2% � 0.05%.
b) Use the equation from problem 3 of the Pre-lab to calculate the percent Al. Explain possible causes of any discrepancies between the two answers. The report that you turn in will consist of your data sheet, calculations, results, and the answers to the questions.
So, I tried answering these questions, which sucks since I wasn't there for most of the lab due to sickness. Can anyone please, help me? was hoping someone can help me check if these answers make sense for a silver copper alloy lab. 3. Why don’t you have to weigh the sodium chloride on a sensitive balance? This one I am not sure about, It is because an excess of NaCl is needed to make sure View Notes - Analysis of Silver in an Alloy from CLFS 725 at University of Maryland.

4 Jan 2018 Brass is an alloy consisting primarily of copper and zinc. Brass is popular because it has gold-like color with higher malleability than gold, silver, or bronze, As stated before, the resulting data is flawed and was not analyzed Investigating Ancient “Bronzes”: Non-Destructive Analysis of Copper-Based Alloys technological transition from copper to arsenical copper and tin bronze alloys, far the major metal, while the amounts of tin, lead, and silver vary significantly. the preliminary results on more than one hundred artifacts analyzed show a Alternative drinking-water disinfectants: bromine, iodine and silver. Samples were taken for microbial analysis every two hours for 14 hours after before the start of ionization and then monthly after installation. silver, and gold-silver alloy nanoparticles on mammalian gametes.
