Bubbling an unknown reactant gas of a chemical reaction through a bottle containing lime water causes the clear liquid to become cloudy as calcium carbonate is precipitated out. This is he classic test for the presence of Carbon Dioxide
how do we test carbon dioxide
I have absolutely no idea. check a textbook or something.
Lime water test.
Use two chemical test. the first place a burning strip of magnesium metal into the suspect gas if in burns bright white and produces a black soot, this indicts carbon dioxide gas. The second test would be to bubble the suspect gas through a solution of calcium hydroxide if the solution turns white and milky, carbon dioxide is indicted.
by the process of photosynthesis
CaCO3 (s) + H2O(l) CaCO3 is a white solid that appears cloudy in solution Limewater is also used in the chemical test for carbon dioxide. The chemical test is if carbon dioxide is mixed with limewater it then clouds. If this happens then the gas will be carbon dioxide.
how do we test carbon dioxide
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!
Bromothymol blue Look it up and you'll get your answer
To prepare and examine carbon dioxide:
To test the presence of carbon dioxide bubble the gas into the lime water. Carbon dioxide reacts to form calcium carbonate which turns cloudy.
limewater turns cloudy in the presence of carbon dioxide
limewater test Ca(OH)2(aq) + CO2(g) ----> CaCO3(s) + H2O(l)
I have absolutely no idea. check a textbook or something.
The gas yielded from a chamical reaction should be allowed to pass through clean lime water. If the gas is CO2, it turns lime water milky by formation of CaCO3. This is the confirmatory test for CO2 gas
Put the gas (CO2) in lime water. If the lime water changes colour, then it means that there is carbon dioxide in the gas depending on how fast the lime water changes colour
It is a test for carbon dioxide.
