How do carbon dioxide and potassium dichromate react?
Any reaction occur.
What gas that passed through into an acidic dichromate solution and turn the solution from orange to green?
Sulphur Dioxide
What are the properties of ethanol in terms of burning and partial oxidation?
Ethanol burns readily in a plentiful supply of air to form carbon dioxide and water. In a very limited amount of air carbon or carbon monoxide may be formed. In the test tube it is oxidised to ethanal and then ethanoic acid by such reagents as acidified potassium dichromate solution. Oxidation to ethanoic acid by oxygen is catalysed by the enzymes in certain bacteria (acetobacter).
Why should the magnesium dioxide precipitate be filtered from the potassium permanganate solution?
Because the magnesium is a 'solid' and the permanganate is a 'liquid'
Why can't potassium hydroxide be used to test for carbon dioxide?
it is because potassium hydroxide will react with carbon dioxide to form potassium carbonate and water. but potassium carbonate is soluble, so there will be no visible change to see if there is carbon dioxide emitted
What happens in a positive test for sulfur dioxide?
The aqueous acidified potassium dichromate(VI) solution turns from orange to green.

Sulphur Dioxide
How would you test for the presence of sulfur Dioxide?
You can attempt to pass the gas into aqueous acidified potassium manganate(VII). Sulfur dioxide turns it from purple tocolourless.It forms a white precipitate of barium sulphate when passed through a solution of barium chloride and chlorine water.

Which gas turns K2Cr2O7 paper from orange to green with chemical equation?
Sulfur dioxide gas turns acidifiedpotassium dichromate(VI) solution from orange to green.Chromium is reducedfrom (VI) to (III). potassium sulfur sulfuric chromium(III) potassiumdichromate(VI) + dioxide + acid sulfate + sulfate + water.
What is the use of potassium carbonate in the preparation of cochineal solution?
synthesized the c olor of cochineal solution because of carbon dioxide
Why does the part of leaf inside the bottle containing potassium hydroxide solution not get carbon dioxide?
i don`t no
Why should the magnesium dioxide precipitate be filtered from the potassium permanganate solution?
Because the magnesium is a 'solid' and the permanganate is a 'liquid'
What Large amounts of atmospheric carbon dioxide are absorbed by what?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
What are large amounts of atmospheric carbon dioxide absorbed by?
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
Is potassium same as silicon dioxide?
No, potassium is an element and silicon dioxide is a compound that forms sand and glass.
