The tarnish removal method used in this experiment uses a chemical reaction to convert the silver sulfide back into silver Many metals in addition to silver form compounds with sulfurField tests for metals in ore rocks Pure silver is the brightest of metals of a brilliant white hue with rich luster To detect chloride of silver in a pulp rub harshly with a clean bright and wet copper cartridge or coin and if there be silver in the pulp the copper will be coated with it Graphite will also whiten copper but the

silver smelting chemical reaction in silver smelting chemical reaction Smelting Wikipedia Smelting is a process of applying heat to ore in order to extract out a base metalIt is a form of extractive metallurgyIt is used to extract many metals from their ores including silver Additives such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfid Once the ores are fully roasted and the sulfur is driven off the extraction of the gold or silver from the ore is not especially difficult

Several processes can then be used to separate the gold from the ore The most common techniques in the United States use cyanide in various ways In one the ground ore is put into a tank containing a weak cyanide solution and zinc is added The zinc causes a chemical reaction which separates the gold from the orePE Silver = barns/electron U=PE Silver x rElectron Density=2 barns/cc Radioactivity GRapi = 0 Gamma Ray American Petroleum Institute Units Silver is Not Radioactive

Another chemical reaction might include silver ions Ag If you mix a solution with silver ions with a solution that has chloride Cl ions silver chloride AgCl precipitate will form and drop out of solution 3 Single reactions often happen as part of a larger series of reactionsThe proportion of silver in these alloys is stated in terms of fineness which means parts of silver per thousand of the alloy Sterling silver contains 925 percent of silver and 75 percent of another metal usually copper ie it has a fineness of 925 Jewelry silver is an alloy containing 80 percent silver and 20 percent copper 800 fine

Chemical properties Silver is a very inactive metal It does not react with oxygen in the air under normal circumstanc It does react slowly with sulfur compounds in the air however The product of this reaction is silver sulfide Ag 2 S a black compound The tarnish that develops over time on silverware and other silver plated objects is silver sulfideWhen refining silver you want to make sure you do this outside where there is plenty of ventilation Give yourself plenty of room in order to have a quicker dissolving reaction from the silver Depending on how much silver you have to refine will depend on how many 5 gallon buckets you will need

When silver is attacked by sulfur the chemical reaction leaves the metal with a brown black patina which does not result in much metal loss The attack also results in black fissures and pits The rate of pitting attack is generally slow but can increase if a stronger acid or salts are presentAug 12 32 I am so bad at this stuff any help would be great PLEASEEEEEEEE Write the balanced equation including phase notation for the reaction of silver metal dropping into hydrochloric acid to produce a white precipitate Is the reaction in question 14 REDOX Explain
