Does potassium nitrate react with water?

No, Potassium Nitrate will not react with water, it will only form an aqueous solution.\n\nKNO3(s) --H2O--> K+(aq) + NO3-(aq)\n\nSince Potassium ions and Nitrate ions form substances which are strong electroltes, both these ions will stay dissassociated in solution and not react with the water.

Yes, the reaction would spontaneously occur because Sn is higher on the activity series than Ag.\n\nSn(s) + 2AgNO3(aq) => Sn(NO3)2(aq) + 2 Ag(s)\nThe net ionic is\nSn(s) + 2Ag+(aq) => Sn+2(aq) + 2 Ag(s)\n\nI don't remember the oxidation number for Sn.  2 sounds about right.\n\nIt would turn a silver nitrate solution to a tin nitrate solution, and you'd see metallic silver precipitate out.

All nitrates are soluble.  You would need to consult a table of solubilities to see what other ions you could use to precipitate out the cations.\n\nEx:  If you had silver nitrate in a solution you could add something with a halide ion such as sodium chloride.  The silver ion would precipitate out with the chloride ion.  If no ppt forms with the sodium chloride you know it was not silver ions.\n\nThen look for other ions that you could test for.

If Br water ismixed with KI the Br will replace the I in KI and make Kbr and free I2(diatomic) It is not terribly soluble in water. It could buble out as a violet gas if the temp were high enough. \n\nIf KF is mixed with Cl water no reaction because Cl will not replace F. They will replace each oter from bottom up. Nothing replaces F.

here's some\nThe main component of the nitrogen cycle starts with the element nitrogen in the air. Two nitrogen oxides are found in the air as a result of interactions with oxygen. Nitrogen will only react with oxygen in the presence of high temperatures and pressures found near lightning bolts and in combustion reactions in power plants or internal combustion engines. Nitric oxide, NO, and nitrogen dioxide, NO2, are formed under these conditions. Eventually nitrogen dioxide may react with water in rain to form nitric acid, HNO3. The nitrates thus formed may be utilized by plants as a nutrient. \n  \nNitrogen in the air becomes a part of biological matter mostly through the actions of bacteria and algae in a process known as nitrogen fixation. Legume plants such as clover, alfalfa, and soybeans form nodules on the roots where nitrogen fixing bacteria take nitrogen from the air and convert it into ammonia, NH3. The ammonia is further converted by other bacteria first into nitrite ions, NO2-, and then into nitrate ions, NO3-. Plants utilize the nitrate ions as a nutrient or fertilizer for growth. Nitrogen is incorporate in many amino acids which are further reacted to make proteins. \n  \nAmmonia is also made through a synthetic process called the Haber Process. Nitrogen and hydrogen are reacted under great pressure and temperature in the presence of a catalyst to make ammonia. Ammonia may be directly applied to farm fields as fertilizer. Ammonia may be further processed with oxygen to make nitric acid. The reaction of ammonia and nitric acid produces ammonium nitrate which may then be used as a fertilizer. Animal wastes when decomposed also return to the earth as nitrates. \n  \nTo complete the cycle other bacteria in the soil carry out a process known as denitrification which converts nitrates back to nitrogen gas. A side product of this reaction is the production of a gas known as nitrous oxide, N2O. Nitrous oxide, also known as "laughing gas" - mild anesthetic, is also a greenhouse gas which contributes to global warming.

For any reaction between a strong base (potassium hydroxide) and a strong acid (nitric acid) the end result is the neutralization of the acid and base to produce water.  The net ionic reaction will always be the same and show the reaction of the acid (H+) with the base (OH-) to form water.  Therefore,\n\nH+  +  OH-  --->  H2O

Potassium Permanganate dissolves easily in water.  Iodine is only slightly soluble in water, but it dissolves really well in non-polar solvents such as ethanol, dichoromethane, etc.

Definitely not water, as those three metals will burn on contact with water (and potassium will explode.) Liquid CO2 might do, as it would cool the burning material extensively, possibly below the ignition point. The sand (SiO2) would be a smothering agent. I'm not sure about the carbon tet.\n\n5 NOV 06, 1522 hrs, GMT.

Without consulting any reaction energy tables, my money's on HNO3.  Nitric acid is one of about a half dozen really strong acids and will give off a tremendous amount of heat when dissolved in water.  I don't think any of these will actually react with water, but nitric acid will certainly dissolve the most violently.  If you have access to reference tables, you'll want to look up reaction enthalpies, or dissolution enthalpies.  \n\nOf the compounds you listed, Ammonia (NH3) is a weak base that will not do anything special when added to water, Nitric Acid (HNO3) is a very strong mineral acid that dissolves exothermically, Sodium Sulfide (Na2S) is an ionic salt that should dissolve without any fireworks, and Hydrogen Cyanide (HCN) is a somewhat weaker acid that I would expect to give off less heat than HNO3 when dissolved in water.

Sodium in it's metallic form is extremely reactive with water.  Setting out some sodium can cause spontaneous combustion if the humidity is high or its sits long enough in moderate humidity.  Pure sodium is extremely reactive.  Sodium salts (like table salt) are much less reactive than pure sodium.  Their reactivities are dependant on the anion... (carbonates, Chlorine, nitrates...)

The solute would the the silver nitrate because it is desolved in the water.  Water would be the solvent.

Salt when dissoved in water dissociates an forms Sodium+ and Chlorine- ions.Sodium in free state immediately reacts with oxygen and burns.That's the reason why sodium is stored under kerosene.When the water containing salt comes in contact with a wound,the Sodium gets deposited on our wounds and starts oxidising and burns our skin which hurts us.

OK....You need to understand how this is all working, and why.  So, the formula equation for this reaction would be something like:\n\nKOH(aq) + HNO3(aq) --> H2O(l) + KNO3(aq)\n\nSince KOH, HNO3 and KNO3 are all strong electrolytes, they are totally ionized when they're dissolved in water.  So, written in complete ionic form, that equation would be:\n\nK+(aq) + OH-(aq) + H+(aq) + NO3-(aq) --> H2O(l) + K+(aq) + NO3-(aq)\n\nTo get to the net ionic equation, you just cross out the things that are the same on both sides of the arrow.  K+(aq) and NO3-(aq) are on both sides, so the net ionic equation is:\n\nH+(aq) + OH-(aq) --> H2O(l)
