Which will not be precipitated after addition of (NH4)2CO3 in presence of NH4Cl 1.Mg 2.Ba 3.Ca 4.Sr?
Verified Answer
Which will not be precipitated after addition of (NH4)2CO3 in presence...
When (NH4)2CO3 is added to salt solution containing NH4Cl and NH4OH, the carbonates of Ba2+, Sr2+ and Ca2+ are precipitated:
BaCl2+(NH4)2CO3 → BaCO3↓+ 2NH4Cl
SrCl2+(NH4)2CO3 → SrCO3↓+ 2NH4Cl
CaCl2+(NH4)2CO3 → CaCO3↓+ 2NH4Cl

Which will not be precipitated after addition of (NH4)2CO3 in presence...
Explanation:
When (NH4)2CO3 is added in the presence of NH4Cl, the following reactions occur:
1. Formation of NH4OH:
(NH4)2CO3 + 2NH4Cl → 2NH4OH + CO2 + 2NH4Cl
2. Formation of Carbonate Complex:
Mg2+ + CO32- → MgCO3 (insoluble)
Ba2+ + CO32- → BaCO3 (insoluble)
Ca2+ + CO32- → CaCO3 (insoluble)
Sr2+ + CO32- → SrCO3 (insoluble)
Explanation for each option:
1. Mg:
- When (NH4)2CO3 is added, Mg2+ reacts with CO32- to form MgCO3.
- MgCO3 is insoluble and will be precipitated.
- Therefore, Mg will be precipitated.
2. Ba:
- When (NH4)2CO3 is added, Ba2+ reacts with CO32- to form BaCO3.
- BaCO3 is insoluble and will be precipitated.
- Therefore, Ba will be precipitated.
3. Ca:
- When (NH4)2CO3 is added, Ca2+ reacts with CO32- to form CaCO3.
- CaCO3 is insoluble and will be precipitated.
- Therefore, Ca will be precipitated.
4. Sr:
- When (NH4)2CO3 is added, Sr2+ reacts with CO32- to form SrCO3.
- SrCO3 is insoluble and will be precipitated.
- Therefore, Sr will be precipitated.
Conclusion:
All the options mentioned (Mg, Ba, Ca, and Sr) will be precipitated when (NH4)2CO3 is added in the presence of NH4Cl.
