Depends what it is? Cu2(OH)3Cl Is insoluble. Is there an acid with it? Or is it just meant to be mixed with water to make a suspension (think cloudy/tiny solid particles in water) rather than a solution? You would want the pure solid in a powder form I imagine. I havenít made these, just helping with the chem :)

I have no experience with the products they sell sorry.

Tropical Fruit Discussion / Help with Inga ID please
« Last post by PltdWorld on Today at 04:08:59 PM »
I have this one Inga remaining from 3 different types of Inga fruit I received several years ago... can't find my notes on the fruit, and I moved the seedlings around so many times there is no way my notes would have held up anyway.  Two of the fruits (pods) were long, one was short and fat... again, no idea which this seedling came from.  It was about 8' tall before I topped it and cut back some of the branches.  Hope someone can help ID.

Copper sulphate is water soluble, and at the concentrations needed  for root pruning, if absorbed by the plant will kill it.

Hmm, I presumed that copper hydroxide was also soluble (and only kept from dissolving by the latex paint).  Apparently it's insoluble.  Okay, well there goes that idea  ;)  Unless I can dig up some sodium hydroxide somewhere to convert it...

Oh hey wait, I have some cement... calcium hydroxide should precipitate out zinc hydroxide....

All three Compunds mentioned by Jose are insoluble ;)


The Oxyclorure I bought is special to be disolved with water, did I buy the wrong one?  ::)

Would not be easier for you to get some Copper oxyclorure? It's the most common copper fungicide here in Europe.

Regarding the plan to precipitate out Cu(OH)2 keep in mind the Zn(OH)2 is only slightly soluble itself so you would need to use an acid or base to dissolve it first. Itís doable but probably not worth the effort if you can find one of the mentioned insoluble Cu compounds locally.

Mikkel, don't you have a friend in the US who could order and send on the seeds to you?

Any updates?
