Add potassium nitrate to distilled water while stirring continuously; stop adding potassium nitrate once the chemical becomes saturated and stops dissolving in the water. Filter the solution into an evaporating dish and measure the temperature of the solution. Measure the temperature and carefully heat the solution under low heat. Weigh the potassium nitrate to determine its solubility. You should find that approximately 36 g of potassium nitrate can be dissolved in 100 ml of water at room temperature (25 degrees Celsius). santosh kumar.batchu santoshkumar@gmail.com
To find the concentration of nitrate ions in the mixture, we first calculate the moles of nitrate ions from each salt using the formula moles = concentration x volume. For potassium nitrate: 0.120 mol/L x volume = moles of nitrate ions. For iron (II) nitrate: 0.160 mol/L x volume = moles of nitrate ions. Add the moles of nitrate ions from both salts to get the total moles of nitrate ions in the mixture. Finally, divide the total moles of nitrate ions by the total volume of the mixture to get the concentration of nitrate ions in the mixture.
To find the molarity, first calculate the number of moles of potassium nitrate using its molar mass (101.1 g/mol). This comes out to 0.2 moles. Then, divide the moles by the volume of the solution in liters (0.250 L) to get the molarity, which is 0.8 M.
I believe the urea eutectic mix as well as those for several other salts are listed in the ASHRAE (American Society of Heating, Refrigerating, and Air-conditioning Engineers) Handbook. http://www.ashrae.org/
it is not illegal to bring it across the border, but if you dont live near a border and cant find it in your local pharmacy/garden center (under the name Saltpeter) or stump remover. you can always buy it online. cost is about $20 and shipping is another $20 so its not cheep but its worth it... if your making smoke bombs... don't use powder sugar... it doesn't work. 3 parts kno3 2 parts sugar. melt at low temp until caramelized then add fuse let harden and light. fun stuff.

For example in nitrates as: sodium nitrate, potassium nitrate, uranyl nitrate, ammonium nitrate, etc.
The reaction between silver nitrate and potassium iodide forms silver iodide precipitate and potassium nitrate. This reaction is a double displacement reaction where the silver ions from silver nitrate switch places with the potassium ions in potassium iodide.
It used to be sold in drugstores; if you can't find it there, try asking the pharmacist.
To find the weight percent of potassium nitrate in the solution, first calculate the total mass of the solution, which is the sum of the mass of potassium nitrate and the mass of water: 30.0 g + 90.0 g = 120.0 g. Next, use the formula for weight percent: (mass of solute / total mass of solution) × 100%. Thus, the weight percent of potassium nitrate is (30.0 g / 120.0 g) × 100% = 25.0%.

potassium nitrate,sulfur, and charcoal.. you can find all kinds of ratios on google.
Well potassium nitrate has a molecular weight of 101. If there are 346g in 750ml there will be 346 x 1000/750 = 461.334 g in 1 liter. The solution is thus 461.334/101 = 4.57 molar (2 decimal places).
Yes. If you mix it with a metal that is higher on the Activity Series of Metals, that metal will replace the lower metal. In our case, Lithium is the only element that is higher than potassium. So, the Lithium would replace the Potassium, forming Potassium and Lithium Nitrate.
calcium carbonate+ nitric acid. a strong acid would replace a weaker acid in most ionic compounds, so you would produce calcium nitrate and carbon dioxide. well, being that nitric acid is widely UNAVAILABLE to most people, it is easy to find potassium or sodium nitrate. if you are going specifically for calcium nitrate you can double displace calcium carbonate with potassium or sodium nitrate resulting in potassium or sodium carbonate and (aq) calcium nitrate. the potassium or sodium carbonate will probably precipitate out much quicker than the nitrate depending on how exact your equation for displacement is. and you should be left with (aq) calcium nitrate. boil off the water and preferably recrystallize for purity. if youre using calcium carbonate just to get any form of nitrate, i recommend simply buying potassium nitrate. if it is not assessable in your area and are trying to get an oxidizer ( i assume thats why you are trying to make a nitrate) i recommend going with a chlorate or perchlorate, these are easier to make at home through electrolysis.
Potassium nitrate or Saltpeter may be used in the salting (pickling of meet foods) but may also be used to make up the critical oxidizing component of gun powder. As such many governments have restriced its public sale due to terrorist threats and it is unlikey to be freely available in our modern world.
Quite a few! 427.4 grams KNO3 (1 mole KNO3/101.11 grams)(6.022 X 1023/1 mole KNO3) = 2.546 X 1024 molecules of potassium nitrate -----------------------------------------------------------
