I want to go ahead and produce like 10 grams of nitrates of each rare earth using the element itself and nitric acid, I don't think I can evaporate
the water solution with heat because I'm not sure at what degree they decompose so I thought of drying them in a bag along with some NaOH and I just
wanted to know if this would work for all the compounds or is it possible that some of them could hang on to water more... tightly lol. I'm not
familiar much with hygroscopic compounds or the chemistry behind it and I only saw dysprosium ntirate and Europium Nitrate being dried with this
method.Eddygp - 15-2-2015 at 05:27
Why don't you try with CaO, CaCl2 or that type of salts? Bear in mind that the NaOH can already have some water inside which reduces its potential
(especially if it is an old sample).blogfast25 - 15-2-2015 at 05:30

They will survive evaporative drying. These nitrates are very hygroscopic though.
