Incompatible Metals Within Solution

Anita was hoping Paul could give her some general information on metals that are not compatible with each other within the same solution. For example, element A causes element B to drop out of solution.

	RE: Incompatible Metals Within Solution Dear Anita,      I recommend you try using our Analytical Periodic Table. Click on any element of interest and see the "Chemical Compatibility" data for the element. The most common compatibility issues we encounter are as follows: • Ag+ and trace Cl1- • SO4= and Pb2+, Ba2+, Cr2O7= • Rare Earth and Alkaline Earth elements mixed with the "fluoride" elements (Ti, Zr, Nb, Hf, Ta W, Si, Sn, Sb, Ge) • "Fluoride" elements mixed with higher amounts of any transition elements, especially Sn and W • Hg at concentrations below 10 ppm or mixed with elements containing organic ligands, such as Antimony Tartrate • Antimony Tartrate in strong (≥ 5%) nitric acid I hope this helps. I look forward to hearing from you if you need further assistance.     Paul R. Gaines, Ph.D. Serving you in chemistry
