Science Experiment Help: What happens when you out galvanized nails in iodine? - what happens to a galvanized nail when it is in vinegar
I tried this laboratory twice and nothing happened. The instructions say to use galvanized nails or screws in a small saucepan. Then add enough iodine to meet almost entirely of nails. Finally, let stand for 30 minutes. My lab sheet will also be recored Idone color when first one has, and after 30 minutes. This is information that tells tihng so I recored assumeing means that iodine is to change colors. But not both of mine do not change the color or change the physical properties at all. Please tell me what to do the mix, and what can not or have not done well in my experiences.

What Happens To A Galvanized Nail When It Is In Vinegar Science Experiment Help: What Happens When You Out Galvanized Nails In Iodine?

I'm not positive, but it is assumed that the iodine was assumed to react.
A couple of things, said that the use of solid iodine or iodine in a solution, maybe a solvent is required to run, too? In addition, all are equal nails or screws? If you have made in their own, they sometimes have a different zinc-coating, like paint or oil, the reaction can be prevented. Some of the nails and screws are layers of metal that resembles the zinc metal, but others may not react with iodine.
I think someone has an explanation about their experiences, the killing is. Your galvanized nail (a source of zinc) back into granular iodine, and there is no reaction - that is exactly what you get.
Add a little water.
You will receive a very strong reaction, the reduction produces entertaining and zinc oxide, and must be very hot (exothermic). This experiment is meant generally to other metals, usually manganese, iron, nickel and aluminum, too, carried out the strengths of the reduction of various metals. But if you do not like ... Just Add Water. Part of iodine solid unreacted gas is converted into iodine, a violet treatment.
The galvanized nails (source of zinc) associated with iodine chemical EquatIon: Zn + I2 ----> ZnI2 Metal
