In chemistry and biology, the prefix “hydr-” is used to designate compounds that contain water as their main component. For example, hydrates are compounds in which water is the main component and other substances are additives. Examples of such compounds include ammonia hydrate, calcium chloride hydrate, etc.

The prefix “hydro-” is also used in chemistry and biology to designate compounds with water as one of their components. For example, sodium bicarbonate (NaHCO3) is a compound in water that is used in the food industry and medicine.

In addition, the prefix “guide-” can be used in other fields, such as hydrodynamics, where it denotes water flows and currents. In this case, the prefix “hydro” can be used to denote hydraulic structures such as dams and dikes.

Thus, the prefixes “hydr” and “hydro” are important and useful elements in scientific and technical fields that help denote water and aqueous liquids. They simplify the understanding and use of various terms and help avoid confusion when describing various substances and phenomena.
