Talk:Potassium oxide

From Wikipedia, the free encyclopedia

I removed this line from the article:

Potassium + Sodum Chloride + Hydrochloric Acid = A VERY BIG EXPLOSION

because (a) it doesn't seem to refer to K2O and (b) it doesn't look like a proper formula. -- Heron

[edit] Not used as a fertilizer

It is a common misconception that K2O is actually used as a fertilizer. It is indeed on the labels of fertilziers, but it just an indicator of how much potassium is present IF it was in the form of K2O. If I recall correctly, it is usually in the form of potash (potassium carbonate), potassium sulfate or potassium chloride.

http://www.sizes.com/materls/fertilizer.htm : "Again, the fertilizer need not actually contain potassium oxide."

Also, K2O reacts violently with water (K2O + H2O --> 2KOH) and I don't see any lilac flames when I use my fertilizer :).

http://scifun.chem.wisc.edu/CHEMWEEK/AgriFert/agrifert.html "The amount of potassium in the fertilizer is the same as it would be if the fertilizer were 15% potassium oxide (K2O)." "Potassium comes from potassium sulfate (K2SO4) or potassium chloride (KCl), which is also called muriate of potash."

I'll work to expand this article entirely and to explain all of this, but I just wanted to let everyone know my logic beforehand. Chris Barile 20:32, 20 February 2006 (UTC)
