Analysis of Silver in an Alloy Introduction In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are

Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big

SUMMARY AND CONCLUSION 6.1 Summary Silver nanoparticles are nanoparticles of silver composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Various shapes and sizes of nanoparticles are synthesized by physical‚ chemical and biological methods. The Chrysophyllum canito leaf extracts were used for silver nanoparticles synthesis. In this study utterly revealed the best milli molar concentrations of silver nanoparticles synthesis in diverse solvents such
