Can remove oxygen and sulphur

D

Can show highest oxidation state of `+7`

Text Solution

Verified by Experts

The correct Answer is:
A, C
Maganese (Mn) imparts hardness to steel as well as removes oxygen and sulphur from steel by forming slag as `MnSiO_(3)`.
`Fe_(2)O_(3)+3Mnrarr2MnO+2Fe`
`MnO+SiO_(2)rarrunderset("(Slag)")(MnSiO_(3))`
