Reagent vs. Solution: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Reagent is a substance used in a chemical reaction to detect, measure, examine, or produce other substances. Solution is a homogeneous mixture of two or more substances, where one is dissolved in the other.
Key Differences
A reagent is a specific type of substance primarily used in chemical reactions to cause, measure, or detect other substances, often marked by its precise chemical composition and behavior. In contrast, a solution represents a more general concept in chemistry, describing a uniform mixture where one substance (solute) is dissolved in another (solvent), regardless of their specific chemical properties.

In laboratories, reagents are often used as benchmarks or catalysts in experiments, meaning their role is more active in influencing chemical processes. Solutions, on the other hand, may simply serve as mediums or environments where these reactions take place, highlighting their more passive role in chemistry.

The preparation of reagents requires strict adherence to formulas and concentrations, as their effectiveness is closely tied to their purity and composition. Solutions, conversely, can vary in concentration and composition while still retaining their basic character, illustrating a more flexible nature.

In terms of storage and handling, reagents demand specific conditions to maintain their efficacy and prevent contamination. Solutions, depending on their components, might not require such stringent conditions, showcasing a difference in practical handling and maintenance.
