Indications:
— In a the first Step by step Applicable It 's, first. The Commission to I think it's better., in which Ions This Salt 'decomposed', Balancing and and then This LProduct of growth to define.
— The of a thickness of not more than 10 mm Other, not elsewhere specified or included – Cations recognition. 'Disintegration' not Continued.
— The Balanced reaction for a (!) Educated particles to formulate!

1. NaCl ⇄ Na⁺ + Cl^–      L_p(NaCl) = c(Na⁺)·c(Cl^–)
2. CaCO₃ ⇄ Ca²⁺ + CO2-3      L_p(CaCO₃) = c(Ca²⁺)·c(CO2-3)
3. CaF₂ ⇄ Ca²⁺ + 2F^–      L_p(CaF₂) = c(Ca²⁺)·c²(F^–)
4. NH₄Cl ⇄ NH+4 + Cl^–      L_p(NH₄Cl) = c(NH+4)·c(Cl^–)
5. AlBr₃ ⇄ Al³⁺ + 3 Br^–      L_p(AlBr₃) = c(Al³⁺)·c³(Br^–)
6. Fe₂O₃ ⇄ 2Fe³⁺ + 3O^2-      L_p(Fe₂O₃) = c²(Fe³⁺)·c³(O^2-)
7. CaSO₄ ⇄ Ca²⁺ + SO2-4      L_p(CaSO₄) = c(Ca²⁺)·c(SO2-4)
