Reactant vs. Reagent

Postby Jynelle Brillantes 1E » Sun Jul 02, 2017 9:33 pm

I’ve noticed both of these terms, on separate occasions, used in limiting reactant problems.

Are they used interchangeably, or is there an important distinction between the two that I should know?

Typically reagent is what you point to in the lab.

Reactant is what you point to in the balanced chemical equation.

Although, this distinction is not often made (and not that important).
As a student I wondered about this for a long time.
Glad you asked.
:-)

As I mentioned in class today, great to see many students answering questions and getting involved in discussion!

Happy 4th!

While they may have different definitions, when they are used in a question, the two terms can essentially be used interchangeably.

Reagents are chemicals that are available for use in the lab. When a reagent is used in a chemical reaction, it is called a reactant.

A reactant is a substance that is consumed in the creation of a product in a chemical reaction. A reagent is used to detect, measure, or produce other substances. In other words, a reagent is a more passive reactant (could be a catalyst?). But for the most part, I believe these words can be used interchangeably.

so you won't get marked down for interchanging them on the tests?

At first I though it was a typo but reactant and reagent are used interchangeably.

Yes, the terms are sometimes used interchangeably, but the distinction lies in that a "reagent" is a chemical that could be used to do a chemical reactant, for example, I have a lot of reagents in the lab in containers. A "reactant" is specifically an active component in a chemical reaction that is moving forward (left hand side of a typical chemical equation).

The two words can be interchangeable and you shouldn't get marked off for using one or the other unless specified.

A reagent is a substance or compound added to a system to cause a chemical reaction, or added to test if a reaction occurs. The terms reactant and reagent are often used interchangeably—however, a reactant is more specifically a substance consumed in the course of a chemical reaction.
