Question

How does passing carbon dioxide through like water make it milky?? Explain.

Answer 1

$\huge\underline\mathfrak{Answer :-}$

Resultant carbon dioxide passed through limewater in the right tube, producing a milky solution due to precipitation of the insoluble suspension of calcium carbonate:

Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O.

The milkiness disappears since calcium bicarbonate is water-soluble.

Answer 2

Answer:

When carbon dioxide is passed through lime water, it turns milky due to formation of white precipitate in form of calcium carbonate
