Answer:

Explanation:

SO2 is a colourless pungent gas which we can test as

follows:

1. Acidic dichromate paper ---orange to green

2. KIO3+ starch solution reagent---SO2 turns filter

paper moistened with KIO3 and starch soln blue.

Lime water reagent SO2 forms white ppt of CaSO3

with lime water.

CO2 being a colourless and odourless gas evolves with

effervescence.

The test reagent for CO2 is lime water or baryta

water.

It forms white turbidity with limewater due to insoluble CaCO3

formation.

Ca(OH)2+CO2 ®¯CaCO3+H2O
