LampPro Tip 1/3

Chemistry Specific

Understand that 'reagent' in chemistry refers to substances explicitly in reactions, not general chemicals.

Illustration for Chemistry Specific
He explained that the reagent would help observe the reaction's color change.
LampPro Tip 2/3

Practical Use

'Reagent' is often used to discuss practical aspects of experiments, such as mixing chemicals.

Illustration for Practical Use
Pour the reagent slowly to avoid a violent reaction.
LampPro Tip 3/3

Experiment Outcome

Reagents are key in determining if a reaction happens, often revealing a substance's presence.

Illustration for Experiment Outcome
The absence of a precipitate confirmed the reagent did not react.

Well, for a long time, since I was in graduate school, I've been messing around making DNA chips -- that is, printing DNA on glass. And that's what you see These little salt spots are just DNA tacked onto glass, and so I can put thousands of these on our glass chip and use them as a detection reagent.
