You can attempt to pass the gas into aqueous acidified potassium manganate(VII). Sulfur dioxide turns it from purple to
colourless.
It forms a white precipitate of barium sulphate when passed through a solution of barium chloride and chlorine water.

What test would allow you to tell the difference between carbon dioxide and nitrogen?
Use limewater. The limewater turns cloudy in the presence of carbon dioxide.
In lead acetate test what element in the amino acid is detected to be present in this test?
Sulfur is the element. The lead-acetate test detects presence of sulfate or sulfide.
What is the reduced sulfur test?
test for amino acids that contain the reduced sulfur group. (:
What is the purpose for iodine test?
The Iodine test is used to test for the presence of starch.
What are the tests of hydrogen and carbon dioxide?
Carbon and hydrogen are detected qualitatively by heating a mixture of the given substance with dry copper (II) oxide in a glass tube. The organic substance is oxidize and carbon dioxide and water are formed. The presence of carbon dioxide is indicated by the formation of a white precipitate of calcium carbonate, when the gaseous products are passed through a solution of lime water. The presence of hydrogen is indicated by the formation of droplets of water in the tube.
What is a carbon dioxide test?
limewater turns cloudy in the presence of carbon dioxide
What test would allow you to tell the difference between carbon dioxide and nitrogen?
Use limewater. The limewater turns cloudy in the presence of carbon dioxide.
How do you do the test for 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.
In lead acetate test what element in the amino acid is detected to be present in this test?
Sulfur is the element. The lead-acetate test detects presence of sulfate or sulfide.
What test would you run to test for the presence of a polypeptide?
Biuret test
What happens in a positive test for sulfur dioxide?
The aqueous acidified potassium dichromate(VI) solution turns from orange to green.
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 substance used to detect the presence of carbon dioxide?
Test for Carbon Dioxide: Bubble unknown gas in lime water. Limewater should go milky if Carbon dioxide is present. Test for water: Add anhydrous copper sulphate crystals (white in colour) to unknown solution. If solution goes a brilliant light blue colour, water is present as the hydrous copper sulphate crystals were formed. Did this help?
What mass do you get when you mix 5 grams of sulfur dioxide with 6 grams of water in a 10 gram test tube?
The mass is 11 g.
What would be the product if a compound containing carbon is burnt. Is there any test to confirm this?
The product of carbon being burnt is carbon dioxide, when it is burnt in excess of oxygen. Carbon dioxide is colorless and basically odorless, but it can be determined by passing the gases into a solution of limewater. This will become milky, as calcium carbonate would be produced in the presence of carbon dioxide.
What does the S.I.M. test for?
Sulfur Indole Motility test
How could the solid calcium hydroxide be used to test for carbon dioxide?
Calcium ydroxide is just another word for "Limewater". Limewater turns milky in the presence of Carbon Dioxide.
