Carbon dioxide
When oxygen reacts with lime water (calcium hydroxide solution), it forms calcium carbonate as a white precipitate. This reaction causes the lime water to turn milky due to the formation of calcium carbonate.
When magnesium is mixed with lime water, no immediate reaction occurs. The white precipitate that forms when lime water reacts with carbon dioxide in the air will not form when magnesium is added.
Limewater is an indicator for Carbon Dioxide
The white precipitate formed when carbon dioxide is added to lime water is calcium carbonate. This reaction occurs because the carbon dioxide reacts with the calcium hydroxide in the lime water to form calcium carbonate, which is insoluble and appears as a white solid.
When sulfur dioxide reacts with lime water (calcium hydroxide), calcium sulfite is formed. This reaction involves the neutralization of sulfur dioxide, leading to the formation of a white precipitate of calcium sulfite. This reaction is the basis for using lime water as a method to detect the presence of sulfur dioxide gas.
Carbon dioxide (CO2) reacts with lime water (calcium hydroxide) to form calcium carbonate, which is insoluble and appears as a milky precipitate. This reaction is often used to test for the presence of carbon dioxide gas.
a precipitate (aqueous -> solid) must be forming
When oxygen reacts with lime water (calcium hydroxide solution), it forms calcium carbonate as a white precipitate. This reaction causes the lime water to turn milky due to the formation of calcium carbonate.
When magnesium is mixed with lime water, no immediate reaction occurs. The white precipitate that forms when lime water reacts with carbon dioxide in the air will not form when magnesium is added.
Limewater is an indicator for Carbon Dioxide
If you blow air into lime water with a straw, the lime water will turn milky due to the formation of calcium carbonate, which is insoluble and creates a precipitate. This reaction occurs as carbon dioxide in the exhaled air reacts with the calcium hydroxide in the lime water to form calcium carbonate.
The white precipitate formed when carbon dioxide is added to lime water is calcium carbonate. This reaction occurs because the carbon dioxide reacts with the calcium hydroxide in the lime water to form calcium carbonate, which is insoluble and appears as a white solid.
Lime water turns cloudy when exposed to air due to the formation of insoluble calcium carbonate. Carbon dioxide in the air reacts with the calcium hydroxide in the lime water, forming calcium carbonate, which is insoluble and appears as a cloudy precipitate.
ime water can be used to detect the presence of carbon dioxide because lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate:Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) no, lime water doesn't produce carbon dioxide, it just detects it.
When sulfur dioxide reacts with lime water (calcium hydroxide), calcium sulfite is formed. This reaction involves the neutralization of sulfur dioxide, leading to the formation of a white precipitate of calcium sulfite. This reaction is the basis for using lime water as a method to detect the presence of sulfur dioxide gas.
When carbon dioxide is passed through lime water, it forms calcium carbonate, which makes the solution turn chalky or cloudy. This reaction occurs as the carbon dioxide reacts with the calcium hydroxide in the lime water to form the insoluble calcium carbonate precipitate.
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
