1.	List out the material for the experiment “when Hydrochloric acid reacts with NaHCO3 and evolves CO2 “. Write the experimental procedure.
Answer» Required material : Stand, test tubes, delivery tube, thistle funnel, two hole rubber corks, Ca(OH)₂ , NaHCO₃, HCl. Experimental procedure : 1. Take NaHCO₃ in a test tube and fix two hole cork to the test tube. 2. Fix thistle funnel in one hole of cork and insert delivery tube in the second hole of the cork. Insert the second end of the delivery tube in the other test tube which is containing Ca(OH)₂ /lime water. 3. Pour dil. HCl into the test tube using thistle funnel. 4. Due to chemical reaction, gas is evolved and pass into the Ca(OH)₂ through delivery tube. It turns in to milky. We can conclude that it is CO₂ gas.
