Determining the Concentration of a Solution: Beer's Law

A set of flashcards based on the concepts related to Beer's Law and the determination of solution concentration through spectrophotometry.

Beer's Law

A relationship stating that absorbance is directly proportional to the concentration of a solution.

Absorbance (A)

The measure of the amount of light absorbed by a solution.

Transmittance (T)

The measure of the amount of light that passes through a solution.

Molar Absorptivity (ε)

A constant that indicates how strongly a substance absorbs light at a given wavelength.

Path Length (b)

The distance that light travels through the solution, usually in centimeters.

Standard Solutions

Solutions of known concentrations used to create a calibration curve.

Cuvette

A small, rectangular container used in spectrophotometry to hold liquid samples.

Aliquot

A portion of a larger whole, often used for analysis.

Spectrophotometer

An instrument used to measure the intensity of light absorbed or transmitted by a solution.

Dilution

The process of reducing the concentration of a solute in a solution.
