You are not going to be able to buy nitric acid above 70% pure.  Nitric acid pretty much dissolves anything it comes in contact with which causes for its low purity.  I would not suggest heating concentrated acid since the fumes it will produce are very dangerous.  The fumes at room temperature will even cause burns. Depending on what you are trying to do, the acid will need some oxygen to dissolve metals.  With stainless steel, a small scratch on the surface will be enough.

I'm not familiar with this material, but sometimes websites that give info on materials and compounds include IR-specs.  Or, if you have a sample, call your local university.  Some one may be able to help you there.

Metal prices will vary depending on how rare they are (gold, for instance, is quite rare), what the demand is for the metal is (certain metals have important uses in semiconductors and therefore are valuable), how easy it is to extract, and the level of quality or purity that is required.

This is really hard to answer. It's not like there is some New York Element Exchange where traders buy and sell elements. If you mean what is the monetary value of an element, there are some that are pretty easy to determine,  since metals like gold, silver, platinum, palladium, aluminum, copper, and other metals are used in industry. But if you want to know the cost of hafnium, then you aren't going to find any one answer, if you can find one at all. \n\nIf you want to see what the metals market prices are go here:http://www.metalprices.com/\nThat will give you most of them. If you want to see the cost of gases for industrial use, like nitrogen, oxygen, hydrogen, helium, you'll have to contact someone like Praxair or Airgas to get a quote.\nhttp://www.praxair.com/praxair.nsf/0/6021E2747E378CF285256B9F0070368D?OpenDocument

I don't know about specific laws in the Phillipines, but it will depend on what chemical and perhaps what you're going to do with it. I presume the lab store attendent knew what they were talking about? Lead is a heavy metal and is pretty freely available. Many salts of heavy metals, although fairly dangerous, are usually freely available - for example many chemicals used in photography are salts of heavy metals such as silver, gold, etc. If you order online there will generally be information available about regulations on the site. You should also always look at the MSDS (Material Safety Data Sheet) for a chemical if you are not familiar with it to get information about its risks and how to handle and dispose of it. These can be found online.\n\nI don't know how old you are, but if you are young and are considering this outside the context of school, I would suggest experienced adult supervision.

Best bet would be to compile it yourself.  In US, you can use yellowpages.com to get a listing and contact information for "import/export" companies

Yep, I got it!  Go to www.agropharm.co.uk.  You can check out the prices there and order online or their phone number is also listed.

Just how "pure" do you want it?\nTo what purpose do you intend to use it?  Perhaps if we knew this, we might be able to advise on what types of impurities would be considered acceptable for your application.\n\nThere are numerous inexpensive and easily accessible sources of lead available, but they all contain some degree of impurities.\n\nIf you want ultra pure lead, your best bet (although it will cost you) will be to buy it through a chemical supplier...if they will sell it to you as an individual.\n\nAnother option would be to chemically extract it from lead containing substances.\nLead is not exactly the most reactive metal out there, so it shouldn't be too hard to device a chemical reaction to extract it from a Pb compound.\nFor example, using soluble Lead Nitrate, out could precipitate out Lead metal using a more reactive pure metal.  This process might not be ideal for your particular application, but if you look around and do a bit of research, you might find something acceptable.

Iridiium on the market currently sales for about $1300 an ounce.  The primary use is as an alloy in the tips of ballpoint pens, because of the incredible hardness of the metal- It is also used in smaller amounts in special electrical applications.
