Question

What two acids are mainly responsible for acid rain?

1) HNO₂
2) H₂SO₄
3) H₂SO₃
4) HNO₃
5) HCl
6) H₂CO₃

Answer 1

The two acids mainly responsible for acid rain are sulfuric acid (H₂SO₄) and nitric acid (HNO₃).

Step-by-step explanation:

The two acids mainly responsible for acid rain are sulfuric acid (H₂SO₄) and nitric acid (HNO₃). These acids are formed when sulfur dioxide (SO₂) and nitrogen oxides (NO and NO₂) dissolve in rainwater and react with it. The reactions are as follows:

H₂O(l) + SO₂(g) → H₂SO₃(aq)
H₂O(l) + NO(g) → HNO₂(aq)
HNO₂(aq) + O₂(g) → HNO₃(aq)
