General Principles and processes of Isolation of Elements
medium
The following reactions take place in the blast furnace in the preparation of impure iron. Identify the reaction pertaining to the formation of the slag.
A
$Fe_2O_{3(s)} + 3CO_{(g)} \rightarrow 2Fe_{(l)} + 3CO_{2(g)}$
B
$CaCO_{3(s)} \rightarrow CaO_{(s)} + CO_{2(g)}$
C
$CaO_{(s)} + SiO_{2(s)} \rightarrow CaSiO_{3(s)}$
D
$2C_{(s)} + O_{2(g)} \rightarrow 2CO_{(g)}$
(AIPMT-2011)
Solution
The fusible material formed by the reaction of flux and gangue.
$\mathrm{FeO}+\mathrm{SiO}_{2} \rightarrow \mathrm{FeSiO}_{3}$
$\mathrm{CaO}(\mathrm{s})+\mathrm{SiO}_{2}(\mathrm{s}) \rightarrow \mathrm{CaSiO}_{3}(\mathrm{s})$
