Martin,
Sorry for the delay. The citrate and citric that I used are both hydrated
(i.e. crystalline), so I suppose the citric acid is monohydrate and the
sodium citrate dihydrate. Coated paper should be OK in the dark for a few
days. No further developments since I wrote the article, but maybe you'll
find something! Good luck.
