In gas chromatography, the stationary phase is typically a liquid coated on a solid support.

The strong peak around 1700 cm-1 is characteristic of the carbonyl (C=O) stretch found in ketones.

Ketones typically show a strong absorption around 1700 cm-1 due to the C=O stretching vibration.

A broad peak in this region typically indicates the presence of O-H stretching vibrations in alcohols or phenols.

Fragmentation in mass spectrometry refers to the breaking of molecular bonds to form smaller ions, which helps in identifying the structure of the original molecule.

The term 'm/z' represents the mass to charge ratio of ions detected in mass spectrometry.

A positive result in a precipitation test indicates that specific ions are present in the solution, forming an insoluble compound.

A positive test for ammonium ions typically involves the evolution of ammonia gas when treated with a strong base, indicating the presence of ammonium.

A positive test for sulfate ions typically involves the formation of a white precipitate of barium sulfate when barium chloride is added.

A white precipitate formed when adding silver nitrate to a solution indicates the presence of chloride ions.

Chromatographic retention time refers to the time taken for a compound to elute from the column, which helps in identifying the compound.

Colorimetric analysis refers to determining the concentration of a colored solution, which can indicate the presence of specific ions.

A precipitation reaction refers to the formation of a solid (precipitate) from a solution when certain ions react with each other.

Barium chloride is used to test for sulfate ions, forming a white precipitate of barium sulfate.

Selectivity in qualitative ion analysis refers to the ability to distinguish between different ions in a mixture, which is essential for accurate identification.

The 'fingerprint region' in IR spectroscopy refers to the region between 400-1500 cm-1, where many unique absorption bands occur for different compounds.

The indicator in titration provides a visual signal of the endpoint, indicating when the reaction is complete.

According to Beer-Lambert Law, higher absorbance indicates a higher concentration of the absorbing species.
