The ability to successfully make solutions is a basic laboratory skill performed in virtually all biological and chemical experiments. A solution is a homogenous mixture of solute dissolved in bulk liquid known as the solvent. Solutions can be described by their solute concentration, a measure of how much solute is present per unit of solution. In this video, a step-by-step procedure for how to make a water-based, or aqueous, solution for biological applications is presented. The video...

Source: Laboratory of Dr. Michael Evans — Georgia Institute of Technology A solution is a homogeneous mixture containing some components in small amounts, called solutes, and one component in a large amount, called the solvent. Solid-liquid solutions contain one or more solid solutes dissolved in a liquid solvent. Solutions are ubiquitous in chemistry: they are used to store and handle small amounts of material, carry out chemical reactions, and develop materials with controllable properties.

Many common substances around us exist as a solution, such as ocean water, air, and gasoline. All solutions are mixtures of substances that are composed of varying amounts of two or more types of atoms or molecules. A mixture with a non-uniform composition is a heterogeneous mixture, whereas a mixture with a uniform composition is a homogeneous mixture. The components that make the homogeneous mixture are evenly spread out and thoroughly mixed. A solution is a homogeneous mixture that is...

There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride. This selective solubility...

Enthalpy of Solution

There are two criteria that favor, but do not guarantee, the spontaneous formation of a solution: A decrease in the internal energy of the system (an exothermic change, as discussed in the previous chapter on thermochemistry) An increased dispersal of matter in the system (which indicates an increase in the entropy of the system, as you will learn about in the later chapter on thermodynamics) In the process of dissolution, an internal energy change often, but not always, occurs as heat is...

Its optical action depends on replacing fluids within the specimen and bringing the refractive indices of cellular components closer together. Refractive index describes how much a material bends light. When neighboring structures have more similar optical properties, light scatters less at their boundaries, producing a clearer transmitted-light image and improving access to internal anatomy.
Murray's Clear Solution is typically prepared from benzyl benzoate and methyl salicylate, which provide the medium used to alter the specimen's optical environment. In combination, they support fluid replacement and refractive-index matching rather than merely adding illumination. This chemical basis is important because transparency results from reduced scattering throughout the prepared tissue.
Refractive-index matching matters because differences between cellular components and surrounding fluids can redirect light and obscure internal structures. Reducing those differences allows more light to pass through with less distortion. The resulting improvement is especially valuable when researchers need to observe organization or morphology across an intact specimen rather than interpret isolated sections.
Extensive sectioning separates a specimen into slices, whereas Murray's Clear Solution improves optical access through the prepared specimen so internal structures can be examined with transmitted light. This distinction can preserve relationships among neighboring anatomical features and developmental patterns. It is therefore useful when spatial organization matters, although the approach depends on achieving sufficient transparency for imaging.
The method supports microscopic examination of internal anatomy in small organisms, embryos, parasites, and other prepared tissues. Its value varies with the specimen's organization and the clarity achieved after optical treatment, but the shared advantage is improved visibility through the material. Researchers can consequently inspect specimen-wide morphology instead of relying only on exposed surfaces.
Improved optical access can help researchers assess morphology, developmental patterns, and the organization of structures within a specimen. These observations are made through transmitted-light microscopy, where reduced scattering allows illumination to pass through more effectively. In biology, the approach is therefore relevant to studies that require an overview of internal arrangement without sectioning every structure.
