concentrated
Concentrated is an adjective describing a substance that contains a relatively large proportion of a solute relative to the solvent, or a solution that has had much of its solvent removed. It is often the opposite of dilute. In chemistry, concentration measures how much solute is present in a given amount of solution or solvent. Common units include molarity (moles per liter), molality (moles per kilogram of solvent), mass percent, volume percent, and mole fraction. The concentration can change through processes such as evaporation, distillation, crystallization, or addition of solvent.
In practical terms, many products are sold as concentrates that must be diluted before use, such as
Beyond chemistry, the term can describe focus or intensity, as in a concentrated effort or a concentrated
Safety and handling: more concentrated solutions and reagents can be more hazardous and reactive; appropriate safety
