Question

I got that CO2 and Cl was present, but I just wanted to confirm that this was correct or if I’m missing one handout for their initial concentralions. 4. (5 pts) A student performing this lab experiment receives her Known solution and begins to conduct tests to identify the anions present. The acidification with nitric acid generates bubbles! The addition of aqueous barium nitrate to the remaining solution yields no precipitate The addition of aqueous silver nitrate forms a precipitate. This precipitate and solution is basified with 6M aqueous Cl ammonia and the precipitate completely dissolves. The same solution is re and a white precipitate forms. Which anions were present in the student's unknown? Explain. -acidified with nitric acid

Explanation / Answer

The anions present in the solution are CO32- and Cl- and not CO2 and Cl. Yes, you are correct in identifying the anions.
