Okay, so we did a lab in class with Na2CO3 in BaCl2 first. The reaction formed a white precipitate, and I suppose the products are BaCO3 + 2NaCl. Not sure if NaCl is dissolved or not, or if it was the white precipitate I saw, but anyways, here's my question... We added HNO3 to that new mixture, BaCO3 + 2NaCl, and it DISSOLVED the precipitate. We're supposed to write a net ionic for it, but I'm not sure what it'd be? Could someone help me out?
