Calculate the silver ion concentration in a saturated solution of silver(I) carbonate (K_sp = 8.1 *10^-12).

Question

Quizplus · Accepted Answer

The solubility product (Ksp) of silver(I) carbonate is given as 8.1 × 10^-12. The dissociation of silver(I) carbonate (Ag2CO3) in water can be represented as Ag2CO3(s) ⇌ 2Ag+(aq) + CO3^2-(aq). Therefore, if the concentration of Ag+ is x, the concentration of CO3^2- is x/2, making the Ksp expression (2x)^2(x/2) = 8.1 × 10^-12. Solving for x gives a concentration of Ag+ as 2.5 × 10^-4 M.
