Hello Everyone,
i got to determine the concentration of BaO, CaO and Na₂O in a matrix of BaCl₂, CaCl₂ and NaCl. How could i get to separate eahc and get their content?

Maybe with a gravimetric analysis, you could precipitate the Ba²⁺ as BaSO₄, the Ca²⁺ with oxalate and sodium...hmmmm...hexahydroxoantimonate(V) or uranylacetate? I don't know if it works for sodium ions...

hope I helped, a little .

But dont there will be a problem with the chloride form of those salt.

If you add water to the mixture you can determine sum of oxides with acid/base titration.

Alternatively you may determine sum of chlorides using argentometry.

ok, i already do that before, and wanted some fresh idea on how i could determine each species exactly.

You can determine the metals concentration by the use of AAS, XRF, ICP instrument .
