AI Thread Summary
To separate an aqueous solution containing phosphates, nitrates, and nitrites, one effective method is to first precipitate the phosphates using calcium chloride (CaCl2) or barium chloride (BaCl2). After the phosphates are removed, nitrites can be precipitated using silver fluoride (AgF). For a solution containing only nitrates and nitrites, similar precipitation techniques can be applied, focusing on the specific reagents that target nitrites for separation. The choice of method may depend on the intended purpose of the separation, such as analysis or industrial application.

Hello

If you had an aqueous solution of phosphates, nitrates and nitrites, how could you separate them?

Also, if not answered above, how could you separate a solution of just nitrates and nitrites?

thank-you for you're time

That will depend on many factors. Do you want to separate them for analysis? Or in some industrial process? What are cations present?

I would first precipitate the phosphates with CaCl2 or BaCl2, for example; then I would precipitate the nitrites with, e.g. AgF.
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
