a precipitate (aqueous -> solid) must be forming
Lime water changes from clear to milky/cloudy when carbon dioxide is bubbled in, indicating the formation of calcium carbonate.
It turns from a clear, colourless substance to a cloudy, whitish precipitate
Lime water is a clear and colourless liquid, but when exposed to Carbon Dioxide, lime water turns into a milky solution.
Lime water is nothing but calcium oxide. It is so transperent. When we blow air through it using a straw, then it becomes milky ie white. This is because of formation of calcium carbonate as carbon di oxide right from our blowing air reacts with calcium oxide.
The symbol for lime water is Ca(OH)2. Lime water is a saturated solution of calcium hydroxide in water.
At first, lime water reacts with carbon dioxide to form CaCO3 which is white and insoluble. When more of the gas is passed through, it reacts with the CaCO3 and water to form CaHCO3 which is soluble and clear.
When you slake a lime an leave it for a few months, there will be a layer of water (providing you used a sufficient amount) ontop of the slaked lime putty. this water is limewater and is clear but contains tiny particles in suspension. The putty is what we refer to as slaked lime.

When hydrogen gas is passed through lime water, no immediate change will be observed. Lime water is a solution of calcium hydroxide, which is basic. Since hydrogen gas is neutral, it does not react with lime water to produce a visible change.
*shrugs* idk. if the lime stuff is clear then red but if the lime stuff is green then Santa Claus
Water, I think clear lemon lime soda and probably not the milk and cereal in a bowl

Take a small quantity of quicklime (CaO) in a beaker and add a small quantity of water into it. Quicklime reacts vigorously with water to form a suspension of slaked lime (Ca(OH)2) in water. CaO + H2O = Ca(OH)2 Then leave the beaker containing slaked lime undisturbed for some time. After some time a clear solution is obtained as the suspension of slaked lime settles down. This clear solution is called lime water. Then take the lime water in a test tube and pass CO2 gas through it (or blow exhaled air into the lime water through a glass tube). The lime water turns milky. CO2 gas reacts with lime water to form a white precipitate of calcium carbonate. This white precipitate is called lime stone Ca(OH)2 + CO2 = CaCO3 + H2O
