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
-
A.
calcium carbonate is formed which on reaction dissolves -
B.
calcium hydrogen carbonate is precipitated and then dissolves -
C.
calcium carbonate is formed which on reaction with further carbondioxide forms solube calcium hydrogen carbonate -
D.
concentration of the solution has occurred with the deposition of calcium hydroxide -
E.
the solution has become saturated and solid carbondioxide has been deposited
