Actually hydrogen sulfide is a oxidizing agent so when the bras is oxidize with hydrogen sulfide its convert to brass oxide.

Like iron is reacts with oxides then its changes iron color. Like that brass converts into colorless.

Brass is a compound of cu and zn.

Different substance have different reactivity, so hydrogen sulphide is it's corroded form. Maybe.

How hard is that?

What is its equation?

Why we choose hyroden sulphide? I can't understand. Please anybody help me.

Ankit said:   10 years ago
Because brass is react with sulphide then it will corroded.

Actually, Brass is not a simple metal but an alloy i.e. a mixture of Cu and Zn. Generally sulphur in air is very reactive to copper mixtures. So the answer is B.

Because hydrogen sulphide is an acid. Hence being corrosive.

We can not choose because it can do it.

So can you do something which you can't do it.
