When carbon (IV) oxide gas was passed through aqueous calcium hydroxide a white suspension was formed.
(a) Write an equation for the reaction that took place.
(b) State and explain the changes that would
occur when carbon (IV) oxide gas is bubbled through the white suspension.


Answer:

a)#Ca(OH)_2(aq)+CO_2(g)rightarrow#
#CaCO_3(s)+H_2O(l)#
b)- White precipitate dissolve because the insoluble calcium carbonate is
changed into soluble calcium hydrogen carbonate
