Title: voltaic cell research

a voltaic cell is a system made from attaching two diverse metals jointly and dipping the combined piece into some sort of solution that creates conductive atmosphere, the overall purpose of a voltaic cellular is to convert the chemical reaction between the metals and the answer into an electrical charge, Speculation: the ac electricity produced by magnesium (mg) and cupper = the sum with the voltage produced by magnasium and iron; and iron and cupper Factors:

Independent variable: one metallic use in a single voltaic 50 percent cell: (half of the redox reaction happens at each fifty percent cell, Consequently , we can admit in every single half cell a 50 percent reaction is taking place, when the two halves are connect together with a wire and a salt bridge, and electrochemical cellular is created ) Dependent changing: Voltage

Controlling variables:

Amount of solution; a greater volume on a single side from the cell with the cell would provide more electrons, increasing the potential energy, which increases the voltage. Surface area of cathode and anode; if these two will vary surface area, it should be more electrons could travelling one way more than other ways. To avoid this impacting to my result, Let me keep the surface area areas of the anode and cathode the same. Another important part of this test is width and length of sodium bridge, the size of salt link that I make use of must be same size, I will keep this kind of the same by measuring the pieces of filter paper that form my salt connect the same with ruler. Attention of the solutions has to stay the same as a far more concentrated answer contains more electrons which could travel, elevating the potential energy, which increases the voltage. I will measure the attentiveness of the alternatives before the try things out to ensure that these are the same. Equipment required:

5. Lead

2. Zinc

* Iron

2. Silver

* Copper

5. Tin

* Aluminum

* Magnesium (mg)

* Silver precious metal nitrate solution

* Copper...
