 note = {application/pdf, Solubility of neckel ferrites and magnetite was studied the thermodynamically and from the standpoint of dissolution and precipitation reaction at equilibrium. The results suggest that nuckel ferrite dissolves to form nickel ion and ferrous ion, and ferrous ion precipitates to form magnetite : 
NiFe₂O₄+6H⁺+H₂→ Ni²⁺+2Fe²⁺+4H₂O
　　　　　　　　 → 3Ni²⁺+Fe₃O₄+12H⁺+2H₂
　　　　　　　　 → 3Fe²⁺+4H₂O  
Statistical analysis of solubility data from the literatures indicated that the difference in the solubility of ferrous species between nickel ferrite and magnetite was not significant. From these consideration it is conceivable that the solubility of ferrous species from nickel ferrite is the same as that from magnetite.},
