Nitrogen dioxide and sulphur dioxide have some properties in common, which property is shown by one of these compounds, but not by the other?

Options

A. Form's acid rain '
B. Is a reducing agent
C. Is soluble in water
D. Is used as a food preservation

Answer

D

Explanation

Nitrogen dioxide and sulphur dioxide forms acid rain. Acid rain is the water containing sulphuric acid and nitric acid
`NO+O_(3) rarr NO_(2) + O_(2)`
`NO_(2) + 3O_(2) rarr 2 NO_(3) + 2O_(2)`
`NO_(2) + NO_(3) rarr N_(2)O_(5)`
`N_(2)O_(5) + H_(2)O rarr 2 HNO_(3)`
`2 SO_(2) + 2H_(2)O+O_(2) rarr 2 H_(2)SO_(4)`
(b) `NO_(2)` and `SO_(2)` act as a good reducing agent e.g `SO_(2)` reduces halogens to halogen acid `Cl_(2)+2H_(2)O + SO_(2) rarr 2 HCKL + H_(2)SO_(4)`
(c) `NO_(2)` and `SO_(2)` both are soluble in water.
(d) , `SO_(2)` is used in the manufacture of sodium bisulphite `(NaHSO_3)` which is used as a preservative for jams, jellies and squashes.
