Misch metal, an alloy used in making flints and in alloy steels, consists mostly of lanthanoid metals together with about 5% of

Azinc
Biron
Ccopper
Daluminium

Answer: B

Misch metal is about 95% lanthanoid metals (mainly Ce, La, Nd) and about 5% iron, with traces of S, C, Ca and Al. Iron is therefore the second major component.

The most common and characteristic oxidation state of the lanthanoids is NEET level
Lanthanoid contraction is mainly caused by NEET level
Among the following, the lanthanoid that commonly shows the +4 oxidation state in addition to +3 is NEET level
Among the following aqueous tripositive ions, the one that is colourless is NEET level
In acidic solution Ce^4+ is a strong oxidising agent even though it has the stable 4f^0 configuration. The best explanation is that JEE Main level
Aqueous Eu^2+ (4f^7) slowly reduces H^+ in dilute acid. The balanced ionic equation with the product in its characteristic state is JEE Main level
