how to analyse sodium suphate in mixture of sodium chloride and sodium sulphate without gravimatric analysis. is there any analytical method?

[AWK]

And what other methods of quantitative analysis do you know?

i know only precipitation method with barium chloride. but i want to know titration method, i search on google but can't find. please help

Classic method for sodium chloride assay - AgNO3 titration. But you need potentiometric electrode for this.  But it also persiptate method) I think gravimetric much easy, if don't have titration eqiupment.

I want assay sodium sulphate not sodium chloride.

Search under barium titrimetric analysis.

If the mixture contains only two substances determining percentage of one means you know the composition.

This is rarely the case in normal samples, but you have not explained if it is a theoretical, made up example, or real life problem, and what are assumptions.

No, you don't need potentiometric electrode.

O, thanks! You're right, Borek!
I forget about indicators methods.
