Question

Which is not a halide ore:-
1)Cryollite 2)Florspar 3)Horn silver 4) Limonite

Also write the formulas of major constituents of all options.

Answer 1

Limonite is not a halide.

Major constituents:-
Limonite (FeO(OH)·nH2O)- composed of hydrous basic iron oxide
Horn silver(AgCl)- contains significant amounts of chlorine(cl) and silver(Ag),sometimes along with some amounts of mercury(Hg),bromine(Br2) and iodine(I2).
Fluorspar (CaF2)- composed of calcium flouride(CaF2).
Cryolite (Na3•AlF6)- contains significant amounts of gibbsite, boehmite and diaspore which are the mineral forms of aluminum hydroxide and have the same formula- Al(OH)3

Answer 2

Answer:

The correct answer is option 4) Limonite.

Explanation:

Main components:-

1) Cryolite $(Na_{3} .AlF_{6} )-$ includes substantial quantities of gibbsite, boehmite, and diaspore which are the mineral structures of aluminum hydroxide and have the exact formula- $Al(OH)3e$ > Furan.

2) Fluorspar $(CaF_{2} )$- composed of calcium fluoride $(CaF_{2} )$.

3) Horn silver $(AgCl)-$ includes substantial quantities of chlorine$(Cl)$and silver $(Ag),$ sometimes along with some quantities of mercury $(Hg),$ bromine $(Br_{2} )$ and iodine $(I_{2} )$ .

4) Limonite $(FeO(OH).nH_{2} O)$ - composed of hydrous basic iron oxide

Therefore, Limonite is not a halide.
