Which colour does the lime water change to when put in oxygen?
Lime water turns milky or cloudy when exposed to oxygen. This is due to the formation of calcium carbonate as the lime water reacts with carbon dioxide in the air.
Why does lime water turn milky when you breathe out in air in it . Name the product formed?
When you breathe out into lime water (which is a solution of calcium hydroxide), it reacts with the carbon dioxide in your breath to form calcium carbonate. This reaction creates a milky white precipitate in the lime water.
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.
How long does it take for lime water to turn milky?
Lime water is calcium hydroxide. When carbon dioxide is bubbled through it forms this precipitate called as calcium carbonate. This doesnt dissole in the water so the lime water bexomes milky.
What happens when exhaled air is bubbled into lime water?
When exhaled air is bubbled into lime water, the carbon dioxide in the exhaled air reacts with the calcium hydroxide in the lime water to form calcium carbonate, which causes the lime water to turn milky or cloudy. This is because carbon dioxide reacts with calcium hydroxide to produce calcium carbonate, water, and heat.
When we blow air through the freshly prepared lime water how much time does lime water takes to turn milky?
When air containing carbon dioxide is blown through fresh lime water, it will turn milky due to the formation of a white precipitate of calcium carbonate. This usually happens almost immediately, within a few seconds to a minute, depending on the concentration of the carbon dioxide in the air being blown.
Is h2co3 soluble?
yes to a certain degree, it makes slaked lime when added to excess water it can make lime water which turns milky when you blow air through it
What happens when lime water is exposed to oxygen?
If it's exposed to pure oxygen then nothing will happen. If it's exposed to air then the carbon dioxide in air will make it go cloudy. Lime water is the test for the presence of carbon dioxide.
What happens when you mix lime water with oxygen?
Well, darling, when you mix lime water with oxygen, a chemical reaction occurs where the lime water turns milky due to the formation of calcium hydroxide. This reaction is a classic test for the presence of carbon dioxide, as the carbon dioxide in the air reacts with the calcium hydroxide to form calcium carbonate, which is insoluble and gives the milky appearance. So, there you have it, a little science magic for your day!
What would be the effect of the gas on lime water?
Gas (I assume you mean air ) contains Carbon dioxide and if you blow Carbon Dioxide into Lime Water, it turns it milky due to the formation of insoluble CaCO3 The equation is Ca(OH)2 + CO2 = CaCO3 + H20
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.
What happen when we put water into lime water?
When water is added to lime water (which is a saturated solution of calcium hydroxide), the calcium hydroxide dissociates into calcium ions and hydroxide ions. This results in the formation of a milky white precipitate of calcium carbonate due to a chemical reaction between the calcium ions and carbon dioxide in the air.
