Explanation:
Lime water turns white when CO2 is dissolved in lime water. It means that carbon dioxide gas was produced by the sprouts. Carbon dioxide is produced by breathing of sprouts which take oxygen and breath out CO2.

Limewater can be used to detect carbon dioxide. If carbon dioxide is bubbled through limewater then it turns from clear to cloudy/milky in colour. This is why limewater used in a simple respirometer can show that more carbon dioxide is present in exhaled air compared to inhaled air.
The freshly prepared lime water is Ca(OH)2 and when CO2 is passed through it, the compound formed is CaCO3 which forms insoluble precipitate that is white in colour.
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.
