Performed Lab with Na2CO3 in BaCl2 first. The reaction created a white precipitate, and presume the products are BaCO3 + 2NaCl. Not sure if NaCl is dissolved or not, or if it was the white precipitate, however anyways, here's my question. Added HNO3 to that new mixture, BaCO3 + 2NaCl, and it DISSOLVED the precipitate. We're hypothetical to write a net ionic for it, however I'm not sure what it'd be? Could someone help me out?
