Question

What is the saturated concentration of Ag+ (in mol·L–1) if Ag2CO3 is dissolved in a 0.30 M solution of Na2CO3?

Data: For Ag2CO3, the value of Ksp = 8.5 × 10–12 mol3·L–3
Ag2CO3 (s) <-> 2Ag+ + CO32–

Assume complete dissociation of the Na2CO3 as: Na2CO3 (s) → 2Na+ + CO3 2–

A. 4.74 × 10–3
B. 1.52 × 10–4
C. 4.57 × 10–5
D. 5.32 × 10–6
E. 8.45 × 10–7
