Dear list

I'm mixing ferric oxalate solution from powder and it just isn't going into solution. I used 27g ferric oxalate with 4.8g oxalic acid and 2g EDTA (Na4). I used hot distilled water to 50ml. I've been stirring for 3/4 hour and I still have a yellow green opaque liquid and my hand is about to fall off. Is it normal to take so long? Can I reheat a little? Any tips/ideas?

Thanks

John.
