Answer 1

Answer:

Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3. Adding more carbon dioxide results in the precipitate dissolving to form a colourless solution of calcium hydrogencarbonate.

Explanation:

a.If CO2 is bubbled through lime water it reacts with the calcium hydroxide to produce calcium carbonate. ... So if carbon dioxide gas is bubbled through a clear, colorless solution of lime water, the water will become hazy and milky colored as the calcium carbonate precipitates as a white solid suspended in the water.

b.What happens when carbon dioxide gas is bubbled through lime water in small amount ? Solution : When excess of CO2 is passed through lime water the white precipitate of CaCO3 dissolves to form calcium hydrogen carbonate.

What happens when carbon dioxide gas is bubbled through lime water

1. in small quantity

2.in large quantity

$\huge\underline\mathbb\blue{Answer}$ $\huge\red{\ddot\smile}$

What happens when carbon dioxide gas is bubbled through lime water in small amount ? Solution : When excess of CO2 is passed through lime water the white precipitate of CaCO3 dissolves to form calcium hydrogen carbonate.

When Co2 in large quantity is passed through lime water in excess, the turbidity disappears as calcium bicarbonate gets formed which is soluble in water and hence a clear solution is observed
