What substances are totally soluble and burn bright Orange?
352395
Any soluble sodium compound like sodium chloride, sodium acetate, sodium bicarbonate (sodium hydrogen carbonate), sodium carbonate, things like that turn a flame yellow-orange.  \nSoluble calcium compounds like calcium nitrate burn red-orange.

Copper (II) nitrate, Cu(NO3)2, is dark blue.\nBarium nitrate, Ba(NO3)2, is white.\nIron (III) nitrate, Fe(NO3)3, is purple-greenish.\nLead (II) nitrate, Pb(NO3)2, is clear or white.\n\nNot sure what the orange is, but it's not one of those.

One orange has about 100 calories. Also has 4g fiber, 160% Vitamin C, 7% Calcium. I average about 2 everyday! Love it!

You can go to the store and pick up regular table salt.  The sodium in the salt will produce  really cool looking red flame.  Also, calcium containing salts can produce a deep orange/red flame.  You can try tums.  Try grinding it up into a powder form.  Tums usually contains magnesium. I doubt that any salt will burst you into flames!

any oxidative substance (potassium permanganate), ultraviolet rays, sun, air, hydrogen peroxide, etc

Because of the chemical composition in them? May be lemon or orange? they contain more acid.

Hi xighlun,\n\nFRUCTOSE (one of the major sugars found in orange juice) is of key importance in the rate of decomposition of Vit C in orange juice: high levels of fructose drive high rates of decomposition of ascorbic acid (Vit C).  On the other hand, high levels of citric acid and malic acid tend to stabilise Vit C (act to slow the rate of decomposition).\n\nBecause fructose is already a major component in the juice, you cannot prevent decomposition - it occurs naturally, due to reactions between the sugar and the ascorbic acid, mitigated by the citric and malic acids.  These reactions proceed even whilst the orange is still attached to the tree.  The best we can do in practical terms is to slow the rate of attack by the fructose on the ascorbic acid.  We usually do this by keeping the juice at a very cool temperature.  The ultimate way of achieving the lowest rate of decomposition of Vit C is to concentrate and freeze the juice ASAP after juicing - this is known as FCOJ (frozen concentrated orange juice); the resulting concentrate has the highest retention of Vit C - higher than freshy-squeezed or NFC (not-from-concentrate) juice.\n\nI think the degradation of Vit C generally speaking, would probably occur through oxidation.  This means that looking for the mechanism of degradation in OJ means looking for things in the juice that could act as an oxidant?\n\nU will find plenty of websites on all aspects of chemistry - maybe try googling some obvious keywords, eg: mechanism degradation vitamin c orange juice.

Bleach contains NaCl (table salt), H2O, and NaClO (sodium chlorate).\nIt is the "ClO -" ion in the NaClO that causes things to be bleached and lose its colour.

stolen outright from this page:\nhttp://www.npi.gov.au/database/substance-info/profiles/70.html\n\nPhenol is highly soluble in water. Very soluble in alcohol, chloroform, ether, glycerol, carbon disulphide, petrolatum, volatile and fixed oils, aqueous alkali hydroxides. Almost insoluble in petroleum ether.

any fuel that carries some oxgen with burn clean, such as most Alcohol.\n\nBut depents on what you are burning it with, and what your detection limits are, very diffcult to burn something else withe Alcohol and not leave any residue.\n\nOnly buring the Alcohol all  by itself that you may not leave any residue.

Ah ha.  Thermite.  Magnesium ribbon would be the usual method to start this reaction.\n\nBe careful with this reaction...

I would just recommend looking at a can and seeing what is the propellant.  We could guess all day, but as long as we don't work in a silly string factory we couldn't be absolute.  Alot of that kinf od informations i proprietary.  But how about this:\nPropellant\nSomething that dries fast (isopropyl)\nA plasticizer to keep the goo gooey\nsome other stuff

I think that flame tests always make for spectacular shows; you stick a little bit of white powder with a wooden splint into a flame and get brilliant, vibrant colors.  These are my favorite flame tests:\nSodium: any sodium compound (like sodium chloride, table salt) will yield a yellow-orange color in flame.\nStrontium compounds flame red.\nLithium compounds yield magenta.\nBoric acid makes emerald green. \nCalcium makes red-orange.\nPotassium makes purple. \nThere are a lot of other colored flames you can make with various compounds.

Visible orange light has a wavelength of about 590 nm.\n\nWith natural colouring materials such as paints or crayons, orange is a secondary colour that can be derived from primary colours by mixing red (or more accurately, magenta) and yellow.\n\nOrange pigments are largely in the ochre or cadmium families.  Brown is actually on the orange part (orange + grey) of the colour spectrum.\n\nOrange is both a noun and an adjective in the English language. Both refer primarily to the orange fruit and the color orange, but have many other derivative meanings. Interestingly, the color was referred to (in Old English, before the English-speaking world was exposed to the fruit) as geoluhread, which transliterates into Modern English as yellow-red or yellored (both pronounced the same).\n\n— Color coordinates — \nHex triplet #CC5500 \nRGBB (r, g, b) (204, 85, 0) \nCMYKH (c, m, y, k) (0, 58, 100, 20) \nHSV (h, s, v) (25°, 100%, 80%)

From a "Dangerous Goods" standpoint :\n\nFlammable materials have a flash point below 61°C. So, most common solvents (Stoddard solvent, kerosine, petrol, VM&P Naptha) and organic liquids and gases (acetone, ether, nitromethane, methane, ethane, propane, butane, ... up to about nonane) are flammable. Some solids (eg naphthalene) are also flammable.\n\nCombustible materials have a flash point greater than 61°C. So diesel fuel, paper, coal, wood, etc are all combustible.\n\nAlso, don't get confused between explosivity and flammability - many explosives aren't flammable. C4 is an example - it will burn (combust) but requires percussive detonation to make it explode. So here's a tip - don't try to "stamp out" burning C4!\n\nAlso, explosivity may be limited to a certain range of concentrations (expressed as Lower Explosive Limit - LEL and Upper Explosive Limit - UEL). These are usually expressed as the % w/v of the fuel in air, although it is sometimes expressed in relation to the oxygen content.
