Question

A solid is a mixture of Na2CO3 and Na2SO3. It is warmed with dilute H2SO4 and the evolved gas mixture is to be tested for CO2 in the presence of SO2. Which procedure gives a valid proof of CO2?

Accepted Answer

Pass the gas first through acidified K2Cr2O7 solution (turning green) and then through lime water

Answer

Pass the gas through conc. H2SO4 and then through lime water

Answer

Pass the gas through BaCl2 solution and then through lime water

Answer

Pass the gas directly into lime water
