Steady-State Approximation in Chemical Kinetics

Steady-State Approximation in Chemical Kinetics

In cases where a reaction mechanism comprises multiple steps with comparable rates, identifying the rate-determining step can be challenging. Nonetheless, an intermediate compound is present in certain stages of the process. An intermediate refers to a chemical species that is … Read more

Atomic Structures And Properties

Atomic Structures And Properties

Atomic structure is the arrangement of subatomic particles within the atom. An atom is a complicated configuration of negatively charged electrons grouped around a positively charged nucleus in certain shells. Protons and neutrons make up the majority of the atom’s … Read more

Atomic Absorption Spectrophotometry: Principle, Parts, Uses

Atomic absorption spectrophotometry

Atomic absorption spectrophotometry is a widely used analytical technique that involves the measurement of the absorption of electromagnetic radiation by atoms in the gas phase. Spectrophotometry is a scientific technique that involves the determination of the concentration of elements present … Read more

Emulsion: Definition, Properties, Types, Uses

Emulsion

Emulsions are heterogeneous mixtures composed of two or more immiscible liquids, where one liquid is dispersed in the form of tiny or even ultramicroscopic droplets that are distributed throughout the other liquid. These structures are typically generated through the incorporation … Read more

Sublimation: Examples, Application, Phase Diagram

Sublimation Definition, Examples, Application, Phase Diagram

When a substance changes directly from its solid state to its gaseous state, this transition is known as sublimation in the chemical sciences. Crystalline iodine and solidified carbon dioxide are chemicals that sublimate at standard ambient temperatures and atmospheric pressure. … Read more

Atomization Methods Used in AAS: Advantages, Disadvantages

Atomization methods used in AAS

Atomization is the process of producing atoms available for absorbance measurement. Atomic absorption analysis is based on generating and supply of free analyte atoms in the ground state to light the element’s characteristic wavelength. Atomic absorption spectrometry, like other spectrochemical techniques, is used to … Read more
