What is Immersion Oil?

Immersion oils improve the resolution and brightness of images viewed through a microscope, owing to their optical and viscosity characteristics. Microscopy wouldn’t have advanced to where it is today without the use of immersion oil. Without it, the resolving power of light microscopes in revealing the details of cells would have hit a brick wall.  What is the Function of Immersion...

What is a Chemical Change?

A chemical change is a reshuffling of chemicals that happens when a chemical reaction takes place. It can happen in the matter of a few nanoseconds, or it can take decades to occur. And while some chemical changes are dramatic and obvious, others are barely noticeable. Types of chemical change can be classified into common categories. You can also...

What is Solubility?

Solubility is the property of a substance, known as the solute, that allows it to be dissolved in a solvent. Virtually all substances are either partially or completely soluble in a particular solvent.  In many cases, a solute can also be a solvent, based on its proportion with a solute. For example, when there is a higher concentration of alcohol...

What Is a Solvent in Science?

A solvent is a substance that is proportionally greater by volume or mass than the substance it dissolves, which is called the solute.  Solvents can be a gas, a liquid, a supercritical fluid, or even a solid substance. A combination of solvent and dissolved solute is a homogeneous mixture known as a solution. Many industrial processes require one or more...
