  1. could i make kno3 with urea and potash
  2. can u make kno3 from urea and nh4no4 and if u can how would i go by doin it
  3. how many grams are in a molar of Ca(NO3)2 and K2CO3
  4. cool but can i use potash with can CaNO3
  5. can i use potash instead of kcl
  6. quote from http://www.geocities.com/CapeCanaveral/Campus/5361/kno3/ammnit.html You can scale the following up or down. Take 760cc (760g) of water and heat to about 50C. To this water add 3 mole (223.5 grams) of your recrystalized and dried KCl and dissolve. Add 480grams of your Ammonium Nitrate solution. You will now have one liter of water with 3 moles of Ammonium Nitrate and 3 moles of KCl dissolved in it. Note: You won't actually have a liter of SOLUTION as dissolving the salts in the water will increase the volume. If you are using pure Ammonium Nitrate (you did not bother with the 50% solution above) you should take one liter of water, 223.5grams KCl and 240grams solid (pure) Ammonium Nitrate. All of the salts will be dissolved and if not the solution should be heated more untill they are. The solution is now cooled slowly, the slower the better. Slow cooling gets you larger crystals of KNO3 which is desirable as they wash better. When the solution has cooled to room temperature it should be placed in the freezer and cooled to about -12C. Don't let any ice form. If you don't have a freezer it is ok but will get much less KNO3 out, in fact you can improvise your own "freezer" by making a freezing mixture of Ammonium Nitrate and water and putting the container which has your solution sitting in it. The KNO3 will come out of solution. The KNO3 can now be seperated out by filtering through a cloth. The crystals should be squeezed when then are in the cloth to get rid of as much of the liquid as possible. The crystals can now be washed in cold (0C) water by simple putting the cloth containing the crystals into the cold water and moving it up and down a number of times so that the water flows in through the cloth to the crystals. The cloth, still with the crystals in it, it taken out and squeezed so that as much of the washing water is got rid of. The yield of KNO3 is about 175 grams KNO3. The KNO3 should be recrystallized for maximum purity. The liquid that the KNO3 has come from will have KNO3 and Ammonium Chloride dissolved in it and this can be saved if you want to attempt to take out some Ammonium Chloride from it later. The Ammonium Chloride would be useful if you were making Ammonium Perchlorate from Sodium Perchlorate....but thats another story. could i use CaNO3 instead of nh4no3 in the making KNO3
