Solution: If you take an ionic compound, dissolve it into water, and then carry out the following steps: I. Add 50 mL of 2.0 M Ca(NO 3)2 solution. This produces a white precipitate. II. Next add 50 mL of 2.0 M HCl solution. This causes the precipitate to dissolve and produces a lot of bubbles, but no apparent odor Which of the following anions (from the original ionic compound) would be consistent with these results. a) OH - b) SO4 2- c) S 2- d) CO3 2- e) PO4 3-
