a) A white precipitate is formed
CO2 reacts with Ca(OH)2(aq) to form insoluble CaCO3(s)
b) The white ppt dissolves to form a colourless solution
CaCO3(s) is converted to Ca(HCO3)2(aq) which is soluble
CaCO3 (s) + CO2 (g) + H2O(l)------>Ca (HCO3)2 (aq)
c) Hissing sound.
Effevervesence/Bubbles of colourless gas are seen.
Sodium darts on S.
d) To suck gas produced.
