Copper Salicylate/Cupric Salicylate solubility problem

Apr 2014
Hi all,
I'm having a few problems getting my copper salicylate to dissolve properly. All my preliminary research said that the powder form is soluble in water. However upon my inital testing i found that although some did dissolve it left large amounts of sediment. I tried vortexing the mixture and heating is to help, but with no luck. I thought maybe some kind of acid or alkaline wash, however my chemistry isn't sufficient to start positing why its not dissolving, hence why im here. Any thoughts or comments would be greatly appreciated. The formula is Cu2(C6H5OCOO)2

Many thanks.
