Zumber Posted February 11, 2011 Posted February 11, 2011 hellow guys,I am facing with problem of identifying the chemical whether it is sodium chloride or sodium oxalate.I have got one chemical i know it's name in our language but wanna it's pyrotechnic name.1) it is white in colour ,crystline,absorbs water quickly when exposed to air,odourless2)extremely cheap it will cost 50 INR for 1kg.3)it producess extremely gold colour when mixed as fallow above chemical....7partskno3........1partssulphur.....1partscharcoal(air)......1partsmixed magnesium(0.5 coarse+0.5fine)coated....1partsrustling sound is there.. unfortunately ihaven't got camera it's unable to post video..help me
NightHawkInLight Posted February 11, 2011 Posted February 11, 2011 If it burns in those ratios my guess is it's sodium nitrate. If it's not an oxidizer I don't think a composition like that would ignite at all.
oldguy Posted February 11, 2011 Posted February 11, 2011 I think NightHawk is right, but I'm a newbie, so take my opinion with a grain of salt. Sodium Chloride NaCl (Table Salt)CAS: 7647-14-5; EC: 231-598-3. Synonyms: Salt, sea salt, common salt, dendritis, rock salt, saline, halite. Stable. Incompatible with strong oxidizing agents. Appearance: colorless crystals or white powder; Melting Point: 804° C; Boiling Point: 1413° C; Vapor Pressure: 1 mm Hg at 865° C ;Specific Gravity: 2.16 g cm3; Solubility in Water: 35.7g/100g at 0° C. Sodium Oxalate NaC2O4 (ethandioic acid disodium salt; disodium salt oxalic acid) MW: 134.01; CAS: 62-76-0. Yellow color agent, delay comps, flash powder, glitter effects with Aluminum and Antimony. Used in Tracer Comps. Melting Point: 250° C - 270° C (482° F - 518° F); Solubility: 3.7g/100g water @ 20° C (68° F). pH: Aqueous solution is neutral. Sodium Nitrate NaNO3MW: 85.01; OB: 47; CAS: 7631-99-4. Synonyms: Nitratine, soda niter, soda nitre, Chile saltpetre, cubic nitre, sodium saltpeter, nitric acid sodium salt. Oxidizer used to make yellow flames. With Magnesium it aids in yellow flare illumination. Used in composite rocket fuels. Very similar to Saltpeter (Potassium Nitrate). It is used where large amounts of a Nitrate Oxidizer are needed in fireworks and explosives. Strong oxidizer - may ignite flammable material. Can be found Over the Counter as ‘Solid OX’ Pellets used for outdoors cooking. It will absorb water as do other Sodium salts. Stable. Incompatible with cyanides, combustible material, strong reducing agents and Aluminum. Harmful if swallowed. Skin, eye and respiratory irritant. Appearance: Colorless crystals or white powder; Melting Point: 306° C; Vapor Density: 2.9 (air = 1); Density (g cm-3): 2.26; Water solubility: Soluble.
Mumbles Posted February 11, 2011 Posted February 11, 2011 Oldguy, I'm not sure where you got that information, but sodium oxalate solutions are distinctly basic. If you have any soluble barium, calcium or strontium salts (the nitrates or chlorides generally), and mix the above unknown salt with them you will be able to tell. Sodium chloride or sodium nitrate will not do anything. Sodium oxalate will precipitate the calcium/strontium/barium. If you think it is sodium nitrate, try mixing 50/50 by weight and see if it burns. Only sodium nitrate will burn.
