Can someone explain the answer to this question please? Not quite understanding the concept here...Thank You!
Which 0.1 M cation solution, when added to a 100 mL 0.1M Na2CO3 dropwise, would form a precipitate first?
Which 0.1 M cation solution, when added to a 100 mL 0.1M Na2CO3 dropwise, would form a precipitate first?
- A. Mg2+ (Ksp MgCO3 = 1.0 × 10–5)
- B. Ca2+ (Ksp CaCO3 = 5.2 × 10–12)
- C. Hg22+ (Ksp Hg2CO3 = 9.0 × 10–17)
- D. Ba2+ (Ksp BaCO3 = 2.0 × 10–9)
- E. All would form a precipitate at the same rate since all are 2+ ions.
