Roasting is a process in which the ore (...

Roasting is a process in which the ore (mostly sulphide) is heated strongly in the presence of excess of air. The heating should be done at a temperature below the melting point of the ore.
`2PbS + 3O_(2) rarr A + 2SO_(2)`
The name of `A` is.

A

Litharge

B

Galena

C

Sesquioxide

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`2PbS + 3O_(2) rarr underset((A))(2PbO) + 2SO_(2)`
Hence, `A` i.e. `PbO`, commonly known as litharge.
