  • Waiting for answer Solutions of barium nitrate and sodium sulfate are mixed, an...

    Barium sulfate is the only compound that precipitates because the other product is sodium nitrate, which is soluble. The overall equation is: ##Ba(NO_3)_(2(aq))+Na_2SO_(4(aq))rarrBaSO_(4(s))+2NaNO_(3(aq))## All nitrates are soluble so the sodium and nitrate(V) ions remain in solution. They take...
