Question
Addition of high proportions of manganese makes steel useful in making rails or raolroads, because manganese :
Options
A.gives hardness to steel
B.helps in the formation of oxides of iron
C.can remove oxygen and sulphur
D.can show highest oxidation state of + 7
Solution
Both are the functions of Mn in steel, Mn removes oxygen and sulphur as
Fe2O3 + 3Mn → 3MnO + 2Fe
MnO + SiO2 → MnSiO
slag
Fe2O3 + 3Mn → 3MnO + 2Fe
MnO + SiO2 → MnSiO
slag
