Question

Consider the following mineral sphalerite, Limonite, Hametite, Rutile, Bauxite, Casseterite, Calamine, Dolomite. If the number of mineral having metal in +2 oxidation state is x & the number of mineral having metal in +3 oxidation state is y then predict the value of ( y x ​ × 2 ) .

TestHub · Accepted Answer

Sphalerite (ZnS): Zn (+2)

Limonite (FeO(OH)·nH₂O): Fe (+3)

Hematite (Fe₂O₃): Fe (+3)

Rutile (TiO₂): Ti (+4)

Bauxite (Al₂O₃·nH₂O): Al (+3)

Cassiterite (SnO₂): Sn (+4)

Calamine (ZnCO₃): Zn (+2)

Dolomite (CaMg(CO₃)₂): Ca (+2), Mg (+2)

Minerals with +2 metal: Sphalerite, Calamine, Dolomite (x=3)

Minerals with +3 metal: Limonite, Hematite, Bauxite (y=3)

Value = $(\frac{x}{y} \times 2) = (\frac{3}{3} \times 2) = 2$
