Solve this following


The deposition of $\mathrm{X}$ and $\mathrm{Y}$ on ground surfaces is referred as wet and dry depositions, respectively. X and $Y$ are :

  1. $\mathrm{X}=$ Ammonium salts, $\mathrm{Y}=\mathrm{CO}_{2}$

  2. $\mathrm{X}=\mathrm{SO}_{2}, \mathrm{Y}=$ Ammonium salts

  3. $\mathrm{X}=$ Ammonium salts, $\mathrm{Y}=\mathrm{SO}_{2}$

  4. $\mathrm{X}=\mathrm{CO}_{2}, \mathrm{Y}=\mathrm{SO}_{2}$

Correct Option: , 3


Oxides of nitrogen and sulphur are acidic and settle down on ground as dry deposition.

Ammonium salts in rain drops result in wet deposition
