Why lime water turn milky but become clear with excess co2?

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.


What is the difference between slaked lime and lime water?

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.


What color does lime water change to when carbon dioxide is bubbled in?

Lime water changes from clear to milky/cloudy when carbon dioxide is bubbled in, indicating the formation of calcium carbonate.


What happens when hydrogen gas is passed through lime water?

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.

How do you get limestone from quicklime?

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

What happens to the lime water as carbon dioxide mixes?

Why does lime water change?

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.
