Question

1. copper on corrosion obtainwt colour of coating?

2. when substance gains oxygen during reactions, substance is said to be?​

Answer 1

Answer:

1:- The oxidation-reduction reactions of copper metal in the environment occur in several steps. Copper metal is oxidized to copper(I) oxide (Cu2O), which is red, and then to copper(II) oxide, which is black. These three compounds are responsible for the characteristic blue-green patina seen today.

2:- If it loses oxygen, it is being reduced. Oxidation and Reduction always take place together, so that if one substance is oxidized, another is reduced. Using this idea, say which substance is oxidised and which substance is reduced in each reaction.

Answer 2

Answer:

when copper undergoes corrosion it turns green

when substance gains oxygen during reactions, substance is said to be oxidized
