Explanation:

Adding Dilute Sulphuric Acid to Sodium Nitrate.

NaNO3 + dil. H2SO4 → Na2SO4 + HNO3

(above 200°C)

Adding Dilute Sulphuric Acid to Sodium Sulphite.

Na2SO3 + dil. H2SO4 → Na2SO4 + H2O + SO2

The one which turns acidified K2Cr2O7 from Orange to green is Na2SO3.

The one which turns acidified FeSO4 from green to brown is NaNO3 because HNO3 decomposes into NO2 which does it.
