Qualitative vs Quantitative

[Verse 1]
Analytical chemistry asks what’s in a sample,
And how much is there? Let’s make it simple.
Choose a method that fits the question you pursue,
Identify the substance, measure its amount too.

[Chorus]
Qualitative: what is it?
Quantitative: how much?
One tells the kind of substance,
One measures what you’ve got.
Qualitative: name it,
Quantitative: count;
Two ways to understand a sample,
That’s what analysis is about.

[Verse 2]
When identity is the question, qualitative is the way,
It tells the nature of the substance in the sample you survey.
When quantity is the question, quantitative takes the lead,
It determines how much substance is present—that’s what you need.

[Chorus]
Qualitative: what is it?
Quantitative: how much?
One tells the kind of substance,
One measures what you’ve got.
Qualitative: name it,
Quantitative: count;
Two ways to understand a sample,
That’s what analysis is about.

[Outro]
What is it? Qualitative.
How much? Quantitative.
Identify, determine—
Now the difference is clear.
