the answer is B....when excess CO2 is passed inyo lime water, the milkiness dissapear...



Ca(OH)2 + 2CO2 ------> Ca(HCO3)2



or the reaction is a multistep reaction



Ca(OH)2 + CO2 ------> CaCO3 + H2O

CaCO3 results in the milkiness formation

Then in excess CO2 i.e on further addition with CO2;

CaCO3 + H2O + CO2 ------> Ca(HCO3)2

Since, Ca(HCO3)2 is soluble, the milkiness dissapeared

Emmy, u are wrong. Bubbling CO2 into CaOH yields CacO3 to give a milky solution at first. But since it is said dat in excess CO2, d milkiness disappears due to d formation of soluble calcimhydrogentrioxocarbonate(Ca(HCO3)2)

Oh am xo sowie... My school yuh guys ar correct.... Carbon(iv) oxide reacts with calcium trioxocarbonate(iv) to form soluble CALCIUM HYDROGENTRIOXOCARBONATE(IV).... WHEN BUBBLED

Ca(OH)2 CO2----> CaCO3 H2O the answer is D

D is the answer co2 is an acid anhydride can(oh)2 is an alkali it gives salt and water caco3 is a salt
