Re: Radium carbonate: Solubility product

["Bjorn Cedervall" <bcradsafers@HOTMAIL.COM>]

>>But since the Periodic System of Elements is said to have

been proposed mostly because of similarities of various elements I dare to 

draw some conclusions to answer your question:



To my knowledge the solubility of earth alkali element compounds follow a 

straight "line" of declining solubility: Ca-Sr-Ba-Ra. This implies that 

radium will be preferentially precipitated.

Thanks for your comment Franz, What you write is what I also would expect. 

It is just nice to have the numbers if you want to take a scientific 

discussion about it.



Suppose that there are 10 times more radioactive strontium atoms than radium 

atoms in a sample - then what would give the strongest signal from a 

precipitated sample? (Yes, I know that there is more built into this 

question than just Ksp values - I just want to start somewhere)



The reason for me bringing this up is that I wonder what kinds of chemistry 

considerations the TFP investigators had.
