When carbondioxide is bubbled into limewater a white precipitate is formed. If the passage of the gas is continued, the precipitate disappears. The reason for this is
calcium carbonate is formed which on reaction dissolves
calcium hydrogen carbonate is precipitated and then dissolves
calcium carbonate is formed which on reaction with further carbondioxide forms solube calcium hydrogen carbonate
concentration of the solution has occurred with the deposition of calcium hydroxide
the solution has become saturated and solid carbondioxide has been deposited
