I've made up a solution of ammonium nitrate from an instant cold pack, however the solution I've made is slightly cloudy and a dull yellow color. I've put it through a coffee filter once but it hasn't really helped. Is there anyway to purify my solution?

This is not a safe compound to work with. Crystallization could work.

Thanks for the quick reply! What kind of dangers are there when dealing with ammonium nitrate? and by Crystallization are you referring to Recrystallization as described here? http://en.wikipedia.org/wiki/Recrystallization_(chemistry ).

Do you remember April Texas factory explosion? It was the ammonium nitrate. It can explode even when dissolved. Sure, it requires a hot, concentrated solution - but heating and concentrating is what we usually do during crystallization.

And yes, recrystallization in wikipedia is more or less what I am referring to.

Aug 7, 1959. 1:15am 7 tons of ammonium nitrate blew up in Roseburg Or, my home town. 14 killed, 6 blocks of downtown destroyed.

Texas City ~1953 a shipload of Ammonium nitrate blew up killing hundreds and destroyed a large area.

this is dangerous stuff, do not "play" with large quantities.

This is ~ 100 grams and I'll be sure to do it outside.
 

FAQ: Purifiying solution of ammonium nitrate.

What is the purpose of purifying a solution of ammonium nitrate?

The purpose of purifying a solution of ammonium nitrate is to remove any impurities or contaminants that may affect the quality or stability of the solution. This is important for ensuring accurate and reliable results in experiments or industrial processes.

How is a solution of ammonium nitrate purified?

The most common method of purifying a solution of ammonium nitrate is through the process of recrystallization. This involves dissolving the solid ammonium nitrate in a solvent, filtering out any impurities, and allowing the solution to cool and form pure crystals of ammonium nitrate.

What are the impurities commonly found in a solution of ammonium nitrate?

The most common impurities found in a solution of ammonium nitrate are other salts, such as ammonium chloride or sodium nitrate, as well as organic compounds, dust, and other small particles. These impurities can come from the manufacturing process or from storage conditions.

Why is it important to remove these impurities from a solution of ammonium nitrate?

Impurities in a solution of ammonium nitrate can affect the concentration and composition of the solution, leading to inaccurate results in experiments or undesirable effects in industrial processes. They can also cause the solution to become unstable or potentially hazardous.

Are there any safety precautions to take when purifying a solution of ammonium nitrate?

Yes, it is important to handle ammonium nitrate with caution as it is a potentially hazardous chemical. Safety precautions may include wearing appropriate protective gear, working in a well-ventilated area, and following proper handling and disposal procedures. It is also important to be aware of the potential for the solution to crystallize rapidly and cause burns if it comes into contact with skin.
