Q.
Assertion: Copper vessels get covered with green coating in rainy season.
Reason: It is because of the formation of copper carbonate.

1 Both assertion and reason are correct and reason is the correct explanation of assertion.

2 Both assertion and reason are correct, but reason is not the correct explanation of assertion.

3 Assertion is true, but reason is false.

4 Assertion is false, but reason is true.

Copper vessels get covered with a green coating in the rainy season because when copper is exposed to air in rainy season, the metal reacts with moisture and atmospheric gases to form basic copper carbonate.

$B a s i c c o p p e r c a r b o n a t e = \underset{(g r e e n i n c o l o u r)}{C u_{2} C O_{3} {(O H)}_{2}} C u (s) + C O_{2} (g) + \underset{(m o i s t a i r)}{O_{2} (g)} + H_{2} O (l) ⟶ C u C O_{3} \cdot C u {(O H)}_{2} $
