Answer :
Explanation:
Based on the qualitative analysis, the following reactions can be written for the detection of Cl- and CO32- ions:
For Cl- (Chloride ion):
- AgNO3 (silver nitrate) test:
Ag+ (aq) + Cl- (aq) → AgCl (s) (white precipitate)
For CO32- (Carbonate ion):
- HCl (hydrochloric acid) test:
CO32- (aq) + 2H+ (aq) → H2O (l) + CO2 (g) (effervescence/ bubbles)
- CaCl2 (calcium chloride) test:
Ca2+ (aq) + CO32- (aq) → CaCO3 (s) (white precipitate)
Note: These reactions are used to detect the presence of Cl- and CO32- ions in a sample, and are commonly used in qualitative analysis techniques like precipitation reactions and acid-base reactions.
