Question

when sulphur dioxide reacts with water and oxygen in air, it results in the production of— 1. snow 2. acid rain 3. nitrogen oxide 4. carbon dioxide​

Answer 1

Answer:

2. acid rain

Explanation:

the chemical reactions in this process are:

1. 2SO2 + O2 -----> 2SO3.

here, sulphur dioxide in gas phase is oxidised to generate unstable sulphur trioxide.

2. SO3 + H2O ------> H2SO4

inpresence of water, sulphur trioxide is converted readily into sulphuric acid, which is an indication of strong acid rain.
