Aim: To show acid reacts with metal carbonate to liberate carbon dioxide,
 
Material  Required: Na2CO3, Woulfe-bottle, thistle funnel, dil. HCl, gas jar, matchbox, delivery tube bent at two right angles, lime water. 
 
Procedure:
  1. Take two test tubes, label them as A and B. Take about 0.5 g of sodium carbonate (Na2CO3) in test tube A and about 0.5 g of sodium hydrogen carbonate (NaHCO3) in test tube B.
  2. Add about 2 mL of dilute ethanoic to both the test tubes.
  3. Pass the gas produced in each case through lime water (calcium hydroxide solution) as shown in below figure and record your observations.

Reactions involved:

2NaHCO3 + H2SO4 → NaSO4 + 2H2O + 2CO2

Na2CO3+ H2SO4→ Na2SO4+ H2O + CO2

when ethanoic acid reacts with sodium carbonate, then carbon dioxide gas is evolved.
