You can find information on electroplating in any College level General Chemistry book. But you may get a lot more out of looking in the phone book. Most cities have business that do electroplating (typically chrome plating) and they might be willing to help you.

If you are into electrochemistry you could make your own solar cell or a flat panel solar cell. A solar cell is a device for converting energy from the sun into electricity. This project is fairly easy and there are plenty of pics to show you exactly how its done. \n\nAlso read the first source listed first because it tells you things you need to know for the second experiment.

I heard of a way of producing an electric courant by heating on side of a PN jonction made of two different type of metal. \nI also saw a alcool lamp with a collier all around that was producing enough electricity for a radio, that was realy long time ago ( may be 60 years ), that collier was made with near an hundred piece of two metal in alternance, and each jonction was a thermal diode.

hi there, i have a great webpage for you.\n\nthis guy built a "periodic table table" - a big table in his garage made out of wood, and a storage space underneath each element in the table that can be opened up.  inside the box he has stored various samples of that element.  all of this information is online, and includes pictures and information including the price he paid for each one.  it's great.\n\nhere's the site:\nhttp://theodoregray.com/PeriodicTable/\n\nscroll down a bit and click somewhere on the wooden table to see what he has for that element.\n\nEDIT:  i guess i should add, a lot of his samples are listed as "donated" but usually include a link to whatever supplier donated them, and i think you could probably follow the link to find out the cost. \n\nmore info here: \nhttp://theodoregray.com/PeriodicTable/HowToGetOne.html\n\ncheers!

Good question!\n\n  When you have amalgam (metal) fillings , and you bite on aluminum foil, it creates direct-current electricity called "galvanism". Galvanism in this case is cause by two dislike metals coming into direct contact with one another. The metal itself is an excellent conductor of electricity, sending the electrical shock to the nerve of the tooth (teeth). OUCH! I have done this by accident, it is such a jarring pain that I wouldn't do it on purpose if you paid me to! ;)  If she has metal fillings and refuses to believe you about the pain it causes to bite on foil, offer her a piece to chew. She will soon be a believer! (It won't work unless she has metal fillings)It's kinda mean, but it won't cause damage to her. Just shock her a good one!

Well see as though you dont really have much time for a project that involves a control... But here is an awesome listing that has loads of ideas with explicit instructions not to mention material list for a wider variety of projects. Since I have no clue what realm of science you were intrested in... This has a little bit of them all! Good Luck!\n\nhttp://school.discovery.com/sciencefaircentral/scifairstudio/ideas.html

If I've understood what you're asking then:\nA\nCd(s) + Ag2+ -> Cd2+ + Ag(s) \n\nCadmium occurs at Anode and the Silver would deposit on the Cathode\n\nB (I hate Manganese equations and the partial above is incorrect)\n\nMnO2 + 4H+ + 2AgBr -> Mn2+ 2Br- + 2Ag + 2H2O\n\nMnO2 @ Anode\nAgBr @ Cathode\n\nC\n\n(PtCl4)2- + 4Ag -> Pt + 4AgCl \nAg @ anode\n(PtCl4)2- @ Cathode

I had not heard of that info before. \nI would advise you to do what I did - when you wonder about the scientific value of some data you found, run it through the NCBI database. It is the clearinghouse for scientific data. \nI queried "platinum nanoparticles cancer" and found 5 publications. It seems there are Phase I studies about platinum nanoparticles, the main advantage seems to be the drug delivery right to the tumor. However, there does NOT seem any data so far that would support any overwhelming optimism, even if the alternative community sees this differently.\nRead some of the article summaries yourself, they're quite interesting.

You will find all sorts of information by searching "Chernobyl radiation effects."  It's looks rather interesting & so I'm going to read it all now.  It gives many different web sites to chose from.

see the diagrams in the source\n\nBig Idea\nWater is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nKey Concepts\n\n    * Ionic compounds such as salt water, conduct electricity when they dissolve in water.\n    * Ionic compounds consist of two or more ions that are held together by electrical attraction. One of the ions has a positive charge (called a cation) and the other has a negative charge (anion).\n    * Molecular compounds, such as water, are made of individual molecules that are bound together by shared electrons (i.e. covalent bonds).\n\nEssential Questions\n\n    * What happens to salt when it is dissolved in water?\n    * What are electrolytes?\n    * How can we determine the volume of dissolved ions in a water sample?\n    * How are atoms held together in an element?\n\nKnowledge and Skills\n\n    * Conduct an experiment to see that water can be split into its constituent ions through the process of electrolysis.\n    * Prepare and experiment with a 10% salt solution to better understand the process of ion exchange.\n    * Discuss and research the "softness" and "hardness" of water.\n    * Use the periodic table to identify elements and learn their characteristics.\n\nPrior Knowledge\n\n    * Define the difference between ionic and molecular compounds.\n    * Salt consists of sodium (Na) and chloride (Cl).\n    * Water is a tiny, V-shaped molecult with the molecular formula H2O.\n    * A basic understanding of how a battery works.\n    * Atoms are made of a positive nucleus surrounded by negative electrons.\n    * An atom's electron configuration, particularly the outermost electrons, determines how the atom can interact with other atoms.\n    * All matter is made up of atoms.\n    * Atoms of any element are alike, but different from atoms of other elements.\n\nCommon Preconceptions\n\n    * Students may think - "Water is a good conductor of electricity." Water is a very poor "conductor" of electricity. (The ionization constant for water is very small.) The reason it is dangerous to insert a light bulb while standing in a puddle of water is that water is a great solvent for ionic compounds. Tap water and fresh water typically contain dissolved ions in sufficient concentrations to enable the solution to be conductive. However, ions in solution carry the charge and are therefore responsible for the current, not the water itself.\n    * Students may think - "Electrons can flow through solutions." In "conduction of electricity" through solutions, electrons themselves do not pass through the solutions. Rather, the charge balance is maintained in the solution by movement of cations and anions toward the electrodes where charge transfer takes place at the solution interface.\n      Water is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nConcept Map\nThis lesson and activity relates to the branch "Phases of Water" from the comprehensive Aquarius Concept Map - Water & its patterns on Earth's surface.\n\nBackground\nIn chemistry, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. An ionic compound, in this case salt, is dissolved with an appropriate solvent, such as water, so that its ions are available in the liquid. An electrical current is applied between a pair of inert electrodes immersed in the liquid. The negatively charged electrode is called the cathode, and th positively charged one the anode. Each electrode attracts ions which are of

Actually the copper doesn't come directly from the solution...\n\nNot sure how much detail you want, but it does use electroplating.  This means that it uses electricity to plate metal on an object.  The stainless steel object is put on the "positive end" and a lump of pure copper is placed on the "negative end."  A low voltage is used because a high voltage plates too fast, and the layer will peel off quickly.  If copper is the plating, then the solution must be a fairly low-concentration copper sulfate (CuSO4) solution, meaning that copper is the only metal present in the electrochemical cell.  The negative end is called the anode, and this decreases in mass as its copper ions are taken to the positive end -- the cathode.  \n\nThis method of plating multiple metals is actually fairly common, because the properties of each one can be combined.  Nickel can be used for farm equipment and engines because it can withstand a lot of force, silver is used for decoration, chromium is used to withstand a lot of use (like a spoon).  Copper is able to conduct heat and helps food cook evenly.

Man did u luck out running into me, go to www.sciplus.com "American science and surplus", all sorts of abandon science projects, factory over runs, cancelled government orders, motors, solar cells, weird stuff in the science dept, it's a mad doctors dream come true, CHEAP TOO ! check it out, you'll find lots of "COOL" stuff, that has many uses ! I did a hydro-electric demonstration of power application, that was so small, I could do it in a lab sink, E-mail me if you want an "A", it's an easy experiment, inexpensive, looks very sophisticated, yet simply displays the hydro-electric properties of producing low cost, hydro-electric power, using no battery's or electric for assistance, just water, so it's completely SAFE ! works on displaying milli-amps of D.C. power, yet you are still producing (at a very low voltage) power.
