Given is This LProduct of growth of L_p(CaSO₄) = 2·10^-5 mol²/l². It is One Lthe island with c(Ca²⁺)= 10^-2 mol/l and c(SO2-4) = 10^-4 mol/l contains, not saturated, saturated or over-saturated?
Notes : Es Applicable (known masses) the following::
— Satisfied Lthe island ionic product = L_p
— Unsatisfied Lthe island ionic product < L_p
— Over-saturated Lthe island ionic product > L_p

---

Lösung:

Es Applicable:
— CaSO₄ ⇄ Ca²⁺ + SO2-4      L_p(CaSO₄) = c(Ca²⁺)·c(SO2-4)
— Ionenprodukt(CaSO₄) = 10^-2 mol/l · 10^-4 mol/l = 10^-6 mol²/l²
— This means that: 10^-6 mol²/l² < L_p (=2·10^-5 mol²/l²).
— The Lthe island is So what do you mean? not saturated.
