What is Concentration?
Concentration is the amount of solute dissolved in a given volume or mass of solvent or solution. Common units include molarity (mol/L), molality (mol/kg), mass percent (%), and parts per million (ppm). Concentration affects reaction rates, colligative properties, and the position of equilibrium. It is fundamental to quantitative analytical and preparative chemistry.

High concentration solutions are generally more hazardous. Concentrated acids and bases cause more severe burns than dilute versions. Always dilute concentrated solutions carefully — add concentrated solution to water, not water to concentrated acid. Label all solutions with concentration, date, and…
