Q. For purification of alumina, the modern processes most useful when $(i)\$the impurity present is a lot iron oxides and (ii) the impurity present is a lot of silica, are
A) For $(i)\$the Hall’s process; for (ii) Baeyer’s process
B) For $(i)$ Serpeck’s process; for (ii) Baeyer’s process
C) For $(i)$ Hall’ process; for (ii) Serpeck’s process
D) For $(i)\$Baeyer’s process; for (ii) Serpeck’s process
Explanation
(d)
Iron oxide impurity $–$ Baeyer’s process
Silica impurity $–\$Serpeck’s process
