K2O, dangerous or not?
Anybody care to elaborate on the effects of K2O in water. I was under the impression that sulphate of potash was as good as K2SO4. Apparently not?
I have been told by a fellow hobbyist this is not the case. In K2O there are two parts potassium and and one part oxygen. It is this 'free' oxygen in the water that reacts and can make phosphorous and can become unstable creating problems. Personally I cannot see this, but then I am no chemist and apparently this info came via a chemist! I am currently using K2O so natuarally I need some reassurance. I cannot find K2SO4 in the UK, so any help would be appreciated for a source! Confused again.............

I am currently using K2O so natuarally I need some reassurance. K2O is an oxide that is used for "measurement conventions". In this way, various sources of potassium KCl, K2SO4, etc, can be compared. You do not have K2O. Chuck Gadd http://www.csd.net/~cgadd/aqua |

So if I don't have K2O, why is it saying it is K2O on the box?

If you want to test it, take a little on a spoon, and drop it into a shot glass of water on a table at arms length. If it doesn't flash into steam and a boiling concentrated lye solution, it's not K2O. http://www.usask.ca/chemistry/course...sium_oxide.pdf Look at the second page under "chemical dangers". Anyone who'd sell K2O to consumers without serious warning labels deserves a severe beating in a court room. It'll burn your hands/eyes/and lungs. |

I believe you said it was labelled sulphate of potash. That is K2SO4. Chuck Gadd http://www.csd.net/~cgadd/aqua |

That was the confusing part Chuck, on the front of the box it said sulphate of potash, on the rear it said K2O (potassium oxide) nothing on the box that mentioned K2SO4!

If you look under the box with the NPK component analysis, you should see a line labeled "Sources:" That's where it should state Potassium Sulfate, which is K2SO4. __ Alex pcalex (at) hotpop.com |
