This causes the cloudiness. Continued passing of Carbon Dioxide through the cloudy limewater makes the cloudiness dissappear. Due the the formation of soluble Calcium Bicarbonate. Calcium Carbonate + Water + Carbon Dioxide -> Calcium Bicarbonate [CaCO3 + H2O + CO2 -> Ca(HCO3)2 Pretty easy stuff! Now where's my Mars bar? Hahahahaha! Nobody said a year 12 can’t explain it;
