Lösung:

Notes The Participants Ions are Al³⁺ Responsibility. O^2-

1. Al₂O₃ ⇄ 2·Al³⁺ + 3·O^2-
2. L_p = c²(Al³⁺)·c³(O^2-)
3. Es Applicable for The Number of The Particles, Notes '=':
       c(Al₂O₃) = ½·c(Al³⁺) = ⅓·c(O^2-)      
       c(Al³⁺) = 2·c(Al₂O₃)       and:
       c(O^2-) = 3·c(Al₂O₃)       This means that Applicable:
4. L_p = [2·c(Al₂O₃)]² · [3·c(Al₂O₃)]³
5. L_p = 4·27·c²(Al₂O₃)·c³(Al₂O₃) = 108·c⁵(Al₂O₃)
6. c(Al₂O₃) = 5Te roots from (L_p/108) = 5Te roots from (1·10^-33/108) = 9.8·10^-8 mol/l
7. From c=n/V=m/M/V following: …
       m = c·V·M = 9.8·10^-8 mol/L · 1.0 L · 102 g/mol = 9.9·10^-6 g = 1·10^-5 g

Es Solving The Commission So what do you mean? maximum about. 0.00001 Grams Aluminium oxide in a Litre Water. This Salt is Really very Not good Soluble in Water.
