    Guys, does anyone know the answer?

    get the image shows the change in colour of lime water. that is the reaction of carbon dioxide with lime water. what is the likely source of carbon dioxide that reacted with lime water? from screen.

    How does carbon dioxide react with Lime water?

    Open in App Solution

    Reaction of Carbon dioxide with Lime Water:

    Lime water is an aqueous Calcium hydroxide solution that is basic in nature.

    The Carbon dioxide is an acidic oxide of Carbon.

    The Calcium hydroxide reacts with Carbon dioxide to give a milky solution of Calcium carbonate.

    The balanced chemical reaction can be written as:

    Ca(OH)2(s)Calciumhydroxide+CO2(g)Carbondioxide→CaCO3(s)↓Calciumcarbonate+H2O(l)Water

    The above chemical reaction is used for the detection of Carbon dioxide.

    Therefore, lime water reacts with Carbon dioxide to give Calcium carbonate.

    How does carbon dioxide react with limewater ?

    Carbon dioxide reacts with limewater to form calcium carbonate, which precipitates out of the solution. The reaction between limewater, which is a solution of calcium hydroxide, "Ca(OH)"_2, and carbon dioxide will result in the formation of an insoluble solid called calcium carbonate, "CaCO"""_3. Ca(OH)_(2(aq)) + CO_text(2(aq]) -> CaCO_(3(s)) darr + H_2O_((l)) The solution will turn milky due to the fact that calcium carbonate is a white precipitate. This reaction is actually used to test for the presence of carbon dioxide. An unknown gas is bubbled through a solution of calcium hydroxide - if the solution turns cloudy, then the unknown gas is carbon dioxide. If you continue to bubble the carbon dioxide through the limewater another acid - base reaction occurs which results in the precipitate dissolving to give soluble calcium hydrogen carbonate: CO_(2(g))+H_2O_((l))+CaCO_(3(s))rarrCa(HCO_3)_(2(aq)) This is how naturally ocurring acid rain is able to chemically erode limestone resulting in cave formation. When this solution evaporates the reverse reaction occurs resulting in the formation of stalactites and stalagmites.

    Carbon dioxide reacts with limewater to form calcium carbonate, which precipitates out of the solution.

    Explanation:

    The reaction between limewater, which is a solution of calcium hydroxide,

    Ca(OH) 2

    , and carbon dioxide will result in the formation of an insoluble solid called calcium carbonate,

    CaCO 3 . C a ( O H ) 2 ( a q ) + C O 2(aq] → C a C O 3 ( s ) ⏐ ⏐ ↓ + H 2 O ( l )

    The solution will turn milky due to the fact that calcium carbonate is a white precipitate. This reaction is actually used to test for the presence of carbon dioxide.

    An unknown gas is bubbled through a solution of calcium hydroxide - if the solution turns cloudy, then the unknown gas is carbon dioxide.

    If you continue to bubble the carbon dioxide through the limewater another acid - base reaction occurs which results in the precipitate dissolving to give soluble calcium hydrogen carbonate:

    C O 2 ( g ) + H 2 O ( l ) + C a C O 3 ( s ) → C a ( H C O 3 ) 2 ( a q )

    This is how naturally ocurring acid rain is able to chemically erode limestone resulting in cave formation.

    When this solution evaporates the reverse reaction occurs resulting in the formation of stalactites and stalagmites.
