Answer #1

CoS (s) — Cot (aq) + saraz) , Ksp For precipitation to begin Q = [cost] [52] = ksp > 10.0062)(529= 4.0x162=> [S2] = 6.4516x1Comment in case of any doubt.

    Just need the Solubility of SnS2 As discussed in the lab intro, a low concentration of sulfide is needed to precipitate group II ions. This is because the group II sulfides are much less soluble than group III sulfides. Prove this by calculating the molar solubility of SnS2(Sn4+ is a group II ion) and Al2S3 (A1%+ is a group III ion). The Ksp values are given below. Type your answers in the boxes below. SnS2 Ksp = 1 x 10-46...
