Wave-Particle Duality & Solutions

Front

What is wave-particle duality?

Back

Wave-particle duality is the concept in quantum mechanics that every particle or quantum entity can be described as either a particle or a wave. This means that light and matter exhibit properties of both waves and particles.

What is a solution in chemistry?

Back

A solution is a homogeneous mixture composed of two or more substances. In a solution, a solute is dissolved in a solvent.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution. For example, salt is a solute when dissolved in water.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. Water is known as the universal solvent because it can dissolve many substances.

Front

What are spectral lines?

Back

Spectral lines are the distinct lines seen in a spectrum that correspond to specific wavelengths of light emitted or absorbed by an atom. They are produced when electrons transition between energy levels.

Front

What is an emission spectrum?

Back

An emission spectrum is the spectrum of light emitted by a substance when its electrons fall from a higher energy level to a lower energy level, releasing energy in the form of light.

Front

What is the role of electrons in atomic spectra?

Back

Electrons are responsible for the spectral lines seen in emission spectra diagrams. Their transitions between energy levels result in the emission or absorption of light at specific wavelengths.

Front

What happens when an electron drops to a lower energy level?

Back

When an electron drops from a higher to a lower energy level, it emits energy in the form of light, which can be observed as spectral lines.

Front

What is the difference between a concentrated solution and a dilute solution?

Back

A concentrated solution has a large amount of solute relative to the amount of solvent, while a dilute solution has a small amount of solute relative to the solvent.

Front

What is the significance of the unknown emission spectra?

Back

The unknown emission spectra can be used to identify the element present in a sample based on its unique spectral lines.
