Question

The formula of cryolite is: (A)  Na3AlF6  (B)  CaCl2.Al2(SO4)3  (C)  Fe4[Fe(CN)6]  (D)  Al2O3.2H2O

Tardigrade Admin · Accepted Answer

Cryolite (Na3AlF6) is an ore of aluminium. In the Hall process cryolite is used with textA textl text2 textO text3 because cryolite increase the electrical conductivity of cell as textA textl text2 textO text3 is a poor conductor.

Q. The formula of cryolite is:

$N a_{3} A l F_{6}$

$C a C l_{2} . A l_{2} (S O_{4})_{3}$

$F e_{4} [F e (CN)_{6}]$

$A l_{2} O_{3} .2 H_{2} O$

Cryolite $(N a_{3} A l F_{6})$ is an ore of aluminium. In the Hall process cryolite is used with $A l_{2} O_{3}$ because cryolite increase the electrical conductivity of cell as $A l_{2} O_{3}$ is a poor conductor.
