Q. What is the slag formed in the extraction of iron?
AP EAMCET
AP EAMCET 2018
A
$CaO$
B
$CaSiO _{3}$
C
$MgSiO _{3}$
D
$SiO _{2}$
Solution:
Iron ores contain acidic impurities like silica ( $SiO _{2}$, silicon dioxide $)$. These impurities react with calcium carbonate to form molten slag
$\underset{\text{Calcium carbonate}}{CaCO _{3}}+ \underset{\text{Silicon dioxide (Silica)}}{SiO _{2}} \longrightarrow \underset{\text{(Slag)Calcium silicate}}{CaSiO _{3}}+ CO _{2} \uparrow$
