What is observed when carbon dioxide gas is passed through limewater for a long duration?
When carbon dioxide gas is passed through limewater (a solution of calcium hydroxide) for an extended period, the solution initially turns milky due to the formation of calcium carbonate, which is a result of the reaction between carbon dioxide and calcium hydroxide. Over time, if excess carbon dioxide is introduced, the calcium carbonate can dissolve back into the solution, forming calcium bicarbonate. This process can lead to the limewater becoming clear again after the initial turbidity.

What is the gas that bubbles through limewater?
The gas that bubbles through limewater is carbon dioxide. When carbon dioxide is passed through limewater (a solution of calcium hydroxide), it forms a white precipitate of calcium carbonate, indicating the presence of the gas.
Reshma passed a gas through limewater this showed it is limewater what colour did it went?
When carbon dioxide gas is passed through limewater, a white precipitate of calcium carbonate forms, causing the limewater to turn milky.
Why is the presence of oxygen determined by passing it through lime water?
It isn't. Bubbling gas through limewater is a test for the presence of carbon dioxide. If the gas contains carbon dioxide, then the clear solution of limewater will turn a cloudy white.
What is the test for carbon dioxide?
to test for carbon dioxide is already dissolved in limewater , after this shake up the test tube , is it be that carbondioxide is present then two things will happen : 1) the limewater will turn cloudy as co2 is a precipatate is this solution 2)the limewater will begin to show efferevescence now we know gas is present if these two thing happen then there is an extremly high chance that co2 is present.
What does limewater look like?
Lime water is a clear and colourless liquid, but when exposed to Carbon Dioxide, lime water turns into a milky solution.
What is the gas that bubbles through limewater?
The gas that bubbles through limewater is carbon dioxide. When carbon dioxide is passed through limewater (a solution of calcium hydroxide), it forms a white precipitate of calcium carbonate, indicating the presence of the gas.
Which liquid is used to test for carbon dioxide?
Carbon dioxide levels are tested through the blood
What happens to liqiud when testing for carbon dioxide?
Limewater - if you bubble Carbon Dioxide through limewater it will go cloudy!
What is the test for dioxide?
Bubbling through limewater. The gas is present if the limewater turns cloudy :)
What test would allow you to tell the difference between carbon dioxide and nitrogen?
The limewater test can differentiate between carbon dioxide and nitrogen. When carbon dioxide is bubbled through limewater, it turns milky due to the formation of calcium carbonate. Nitrogen will not have this effect on limewater.
How do you test for carbon dioxide when calcium carbonate reacts with acid?
To test for carbon dioxide gas produced when calcium carbonate reacts with acid, you can bubble the gas through limewater. If carbon dioxide is present, it will turn the limewater cloudy or milky due to the formation of calcium carbonate.
Reshma passed a gas through limewater this showed it is limewater what colour did it went?
When carbon dioxide gas is passed through limewater, a white precipitate of calcium carbonate forms, causing the limewater to turn milky.
What is the purpose of limewater in an experiment?
Limewater is used in experiments to detect the presence of carbon dioxide gas. When carbon dioxide is passed through limewater, it causes a chemical reaction that results in the limewater turning from clear to milky white, indicating the presence of carbon dioxide. This property makes limewater a valuable tool for testing the presence of carbon dioxide in various experiments and processes.
What happens to the limewater if the gas is present?
If a gas is present in limewater, such as carbon dioxide, it will react with the limewater to form a white precipitate of calcium carbonate. This reaction causes the limewater to become cloudy or milky in appearance. It is a common test for the presence of carbon dioxide gas.
What happens to limewater when carbon dioxide is bubbled through it and why?
It goes cloudy.
Why is the presence of oxygen determined by passing it through lime water?
It isn't. Bubbling gas through limewater is a test for the presence of carbon dioxide. If the gas contains carbon dioxide, then the clear solution of limewater will turn a cloudy white.
