What is the effect of oxygen on lime water?
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.
What happens when magnesium is mixed with lime water?
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.
What is lime water an indicator for?
Limewater is an indicator for Carbon Dioxide
What is the white precipitate formed when carbon dioxide is added to lime water?
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.
What kind of reaction occurs when sulphur dioxide reacts with lime water?
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.
What reacts with Lime water?
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.
What happens when CO2 is passed through a lime water for a long time?
When carbon dioxide (CO2) is passed through lime water (a saturated solution of calcium hydroxide, Ca(OH)2) for an extended period, it reacts with the calcium hydroxide to form calcium carbonate (CaCO3), which is a white precipitate. Initially, the lime water turns milky due to the formation of this precipitate. Over time, if excess CO2 is introduced, the precipitate can dissolve back into the solution, forming calcium bicarbonate, which is soluble in water.
Why does lime water become clear if you stop blowing air into it?
a precipitate (aqueous -> solid) must be forming
What is the effect of oxygen on lime water?
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.
What happens when magnesium is mixed with lime water?
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.
What is lime water an indicator for?
Limewater is an indicator for Carbon Dioxide
When you blow air into the lime water with a straw what is observed?
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.
What is the white precipitate formed when carbon dioxide is added to lime water?
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.
Why does lime water go cloudy?
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.
Why does lime water absorb carbon dioxide?
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.
What kind of reaction occurs when sulphur dioxide reacts with lime water?
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 do lime water turns chalky?
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.
