Question

I’m going to separate Ba 2+ and Cu 2+ and create a percipitate, which method should I use, and which ion will form the percipitate? And how should I do it?

Is it possible to do it with hydroxide precipitation? Or maby with ammonia? I’m going to separate Ba 2+ and Cu 2+ and create a percipitate, which method should I use, and which ion will form the percipitate? And how should I do it?

Explanation / Answer

Ba2+ and Cu2+ ions can be separated by using Na2SO4 solution.

If we add Na2SO4 solution to the mixture containing Ba2+ and Cu2+ ions. Then Ba2+ reacts with SO4^2- to form a white precipitate of BaSO4.

Ba2+(aq) + Na2SO4 (aq) ----------------> BaSO4(s) + 2Na+(aq)

By the separation of precipitate, in the remaining solution Cu2+ ions are present, can be separated.
