copper sulfate, or Cu(SO4)(aq). The first clue we have that it is, in fact, copper sulfate is its reaction with the ammonia solution. When the deep blue color formed(in the reaction), the solution formed is [Cu(NH3)4](OH)2(aq), which gives off a bluish color. Secondly, upon acidification of [Cu(NH3)4](OH)2(aq), we see the solution become practically colorless again, The third clue when potassium ferrocyanide is mixed with copper sulfate, it also forms a red precipitate. And last but not least, when copper sulfate reacts with steel, which is primarily iron, copper is formed. This is why the steel changed to a bronze like metal.mystery=copper sulfate
When a silver spoon is immersed in aqueous copper sulphate solution, a displacement reaction occurs. The silver spoon will react with the copper sulphate, displacing the copper ions and forming silver sulphate solution. Over time, the silver spoon will start to turn slightly reddish as a thin layer of copper is deposited on its surface.
Oh, dude, if you use a stainless spoon to stir salt into water, nothing too exciting will happen. Stainless steel is pretty resistant to corrosion, so your spoon will be just fine. It's not like the spoon will suddenly turn into a magical wand or anything, it'll just help you mix that salty water like a boss.
After awhile the silver will turn into copper because silver is originated from copper
Nope.
No but copper or brass willNo
Vinegar would turn this piece green quickly if it were silver. If it were stainless -it would not tarnish! Personally I like the 'bite ' method. If it's silver-you can leave a bite mark and if its stainless-there is no give-no indent or mark whatsoever. -Klondike Pete-
Copper metal will turn a silver color when placed in silver nitrate solution due to a displacement reaction where silver ions (Ag+) from the solution form solid silver metal on the surface of the copper.
When copper is added to silver nitrate, a single displacement reaction occurs. The copper will displace the silver in the compound, forming copper(II) nitrate and silver. The silver will precipitate out of solution as a solid.
Yes. Silver tone jewelry will turn your finger green because the metal under the silver tone is probably a brass which contains copper. It is the copper that turns your finger green.
First you put a penny in a glass measuring cup containing vinegar. Then hold it over a stove set at low for 2 min. Finally dip in a plastic spoon and remove the penny it should be silver. P.S If it does not work don't blame me. It's ben 2 years since I've done this.
If a copper coin is dipped in silver nitrate solution for hours or days, the solution will likely turn blue due to the formation of copper(II) nitrate. This reaction occurs as copper from the coin reacts with the silver nitrate in the solution.
A penny can turn silver due to a chemical reaction with substances like vinegar or lemon juice, which react with the copper in the penny to form copper oxide. Copper oxide has a silver color, leading to the appearance of the penny turning silver.
