I recently opened up a old decompressed fire extinguisher out of curiosity. After some research I discovered that the dry powder inside, mono ammonium phosphate, can be used to make beautiful crystals. However, I found this powder to be extremely hydrophobic and could never get its dissolve in water at all. I mean this stuff is amazingly hydrophobic. Its fun to see how it reacts in water. But why cant it dissolve and what kind of preparation of mono ammonium phosphate will dissolve and become crystals?
