Oxygen can not be detected by any direct method but for its detection, some Indirect methods are used.
Methods for detecting Oxygen:
There are three methods or tests for the detection of oxygen in organic compounds
- Heating of Organic compound alone In a nitrogen atmosphere
- oxygen-containing functional groups Test
- Combustion Analysis
The given organic compound is heated alone in a dry test tube usually in a nitrogen atmosphere.
Different tests are applied for the detection of oxygen-containing functional groups like Alcohol (OH), Aldehyde (-CHO), Ketone (-CO-) and Carboxylic acid (-COOH).
The most important test for the detection of oxygen is combustion Analysis, in which the percentage of carbon and hydrogen are determined.
What is combustion?
The burning of a substance in the presence of oxygen is called combustion.
Formula to determine Oxygen:
% O = 100 – ( % C + % H )
