Vedclass · Answer

(A) In the extraction of iron from haematite $(Fe_2O_3)$,the main impurity present is silica $(SiO_2)$,which is acidic in nature.To remove this acidic impurity,a basic flux,limestone $(CaCO_3)$,is added.At high temperatures,$CaCO_3$ decomposes to form $CaO$ $(CaCO_3 \rightarrow CaO + CO_2)$.The $CaO$ (flux) reacts with $SiO_2$ (impurity) to form calcium silicate $(CaSiO_3)$,which is known as slag.Thus,$x = SiO_2$ and $y = CaSiO_3$.

In the extraction of iron from haematite,the impurity $(x)$ of the ore is removed in the form of '$y$'. What are $x$ and $y$ respectively?
