precipitation of Sodiummolibdatedihydrate, this is so weird? - (May/04/2006 )
I have to prepare solution contained 3 M sodium molibdate dihydrate, and 0.4 M coppersulfate. Normally, for the lower concentration, they r all dissolved in dd water. I dont know if this is too high concentration of sodium or something. Do u know if sodium can react with sulfate and precipitate ??? Is it possible?? or why is it precipitated??? I am not chemist, really no idea about the reaction. Thanks
the sodium can reorient with the sulfate but this shouldn't precipitate.
have you already tried to prepare this?
maybe the precipitate is copper molybdate?
