Barium?

Submitted by maa10 on Thu, 07/15/2010 - 12:10

Does anyone have a suggestions for making .35M Ba(NO3)2?
It is precipitating out for us. And it seems that we can only make 0.05M with H20

Thanks,

Barium

We also tried to spot with barium nitrate (0.35 M) and found that it was insoluble. We added Nitric Acid in an attempt to dissolve the solid that remained at the bottom of the volumetric flask but we were unsuccessful. We spotted the plate with the solution anyways, even though the molarity was lower than we intended, and it wasn't very successful.

Hope this helps!
