Description
Organic coordination complex, salt of transitional metal iron, alkaline metal lithium and organic oxalic acid. From water solutions crystallizes as pentahydrate.
Reaction between hydroxide or iron(III) oxide, lithium hydroxide or carbonate, and oxalic acid
Chemical equation:
100.00g of lithium trioxalatoferrate(III) pentahydrate а 18.53g of iron(III) oxide or 24.81g of iron(III) hydroxide, 16.68g of lithium hydroxide or 25.73g of lithium carbonate and 87.79g of oxalic acid dihydrate is required.Add acid to the flask, then add small parts of iron compound with stirring until it will totally dissolve .Add acid to the flask, then add small parts of lithium compound with stirring until it will totally dissolve or, if you use carbonate, until carbon dioxide emission will stop. After reaction will stop, filter the solution and use it for crystal growing.
Reaction between iron(III) hydroxide or oxide and lithium hydrooxalate
Chemical equation:
100.00g of lithium trioxalatoferrate(III) pentahydrate а 18.53g of iron(III) oxide or 24.81g of iron(III) hydroxide and 79.38g of lithium hydrooxalate monohydrate is required.Add to the flask with iron(III) compounds solution a hot lithium hydrooxalate solution with stirring. After reaction will stop, filter the solution and use it for crystal growing.
Reaction between iron(III) hydroxide or oxide, lithium oxalate and oxalic acid
Chemical equation:
100.00g of lithium trioxalatoferrate(III) pentahydrate а 18.53g of iron(III) oxide or 24.81g of iron(III) hydroxide, 35.48g of lithium oxalate and 43.89g of oxalic acid dihydrate is required.Add to the flask with iron(III) compounds solution a hot lithium oxalate and oxalic acid solution with stirring. After reaction will stop, filter the solution and use it for crystal growing.
Notes
Direct sunlight or other sources of ultravioler radiation lead to solution changing color from green to yellow, and also lead crystals to shatter. So solution and crystals should be stored in dark place.
Keep in its original form or under several layers of varnish at average humidity and room temperature. Do not keep crystals near heaters.
