Q: In qualitative analysis, what does the term 'chromatographic retention time' refer to?

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

Steps: 5

Step 1: Understand that chromatography is a technique used to separate different compounds in a mixture.
Step 2: Know that a column is part of the chromatography setup where the mixture is passed through.
Step 3: Realize that each compound in the mixture takes a different amount of time to pass through the column.
Step 4: The time it takes for a specific compound to exit the column is called its 'retention time.'
Step 5: Use the retention time to help identify which compound it is, since each compound has a unique retention time.
