For this problem, we’re being asked to calculate the concentration of silver ion in a saturated solution of silver (I) carbonate.
Saturated means that the maximum amount of silver (I) carbonate is dissolved in the solution. The maximum amount of the compound dissolved is equal to the molar solubility of the compound.
Since the silver (I) carbonate is an ionic compound, it forms ions when dissociating in water. The silver (I) carbonate in water is as follows:
Silver (I) means that silver has a +1 charge. The carbonate ion, CO32–, has a charge of –2:
Ag2CO3(s) ⇌ 2 Ag+(aq) + CO32–(aq)
We can construct an ICE table for the dissociation of Ag2CO3.
Remember that solids are ignored in the ICE table and Ksp expression.
The solubility product constant (Ksp) for silver (I) carbonate is 8.8x10-12. What is the concentration of silver ion in a saturated solution?
A) 5.2 × 10-4
B) 2.1 × 10-5
C) 5.2 × 10-5
D) 1.3 × 10-4
E) 2.6 × 10-4
