Carbon dioxide (CO2)
no..lime water go cloudy only wit CO2 and SO2...
the limewater should go cloudy! i'm not 100percent sure
Limewater - if you bubble Carbon Dioxide through limewater it will go cloudy!
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.
Limewater get milky at the presence of carbon dioxide dissolved in it.
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.
because of the chemical reaction between lime water (calcium hydroxide solution) and carbon dioxide which produces insoluble calcium carbonate and waterCa(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)
it makes the water go cloudy but when it comes to doing the hydrogen test it doesn't do anything
to check if exhaled air has more carbon dioxide
well apparently the water has bubbles or something witch activate the ethanol but i dunno.
to test for carbon dioxide is already dissolved in limewater, after this shake up the test tube, is it be that carbon dioxide is present then 2 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 2 things happen then there is an extremely high chance that CO2 is present I hope this answers any questions about the test for C02 i hope this help remember dont skip school
