Why Water Is Colorless, Odorless and Tasteless

Water forms the greatest part of the earth’s surface, it is integral to human life. It performs many functions including cooking, drinking, washing, irrigation. Human beings rely on water to keep clean and maintain hygiene, they can survive without food, but cannot last for more than 5 days without water. Plants depend on water to grow, those that lack or produce low yield crops. Two gasses make up water, 2 hydrogen ions and one oxygen ion, written as H2O the chemical way. Water has 3 major characteristics: odorless, colorless and tasteless. Tasting water is hard because of the presence of few ions that cannot be combined with proteins to be tasted.

The tongue contains taste buds that taste like any type of material eaten, and they combine with proteins to form compounds that can be sensed by the sensory cells. While drinking water, our saliva mixes with it making it difficult for taste receptors to determine its actual taste whether bitter or sweet. Despite this fact, human beings enjoy drinking pure water to quench their thirst and provide smooth skin. You can distinguish salty water from distilled by drinking, however, you can’t determine the type of taste.

Smelling water is not easy because

Pure water is pale blue because of its ability to absorb longer wavelengths, leaving shorter wavelengths of pale blue. Objects gain color from leaving the wavelength to absorb other wavelengths. The pale blue color cannot be seen because absorption didn’t take place. Water is colorless for its inability to reflect light, there is no color reflected hence water obtains colorless nature.

Smelling water is not easy because water is made up of two gasses present in the air. Your receptors are purely made of mucus, so you cannot smell nor taste water. There has never been a need to smell water, the sensory organ senses the smell of polluted water. Odorless means no smell, you cannot depict whether the smell is good or bad. When poured over a plant or soil, you can sense the taste of that soil. Animals like a goat do produce a bad odor when rained upon, a similar case applies to a hen.

Why Water Is Colorless, Odorless and Tasteless

The human body contains a higher percentage of water compared to blood to regulate body temperature. When admitted, you are put on a drip to increase your water level for water that carries oxygen and nutrients to the cell. It is recommended to drink 8 glasses of water per day to enable the body to function well. Water occupies 71 percent of the earth’s surface, and the gaseous state gives it 3 features. The ions present prevent taste buds from forming compounds with proteins present in the tongue. This ensures water has no taste, you can’t depict which taste water produces.

Its colorless nature has been argued by scientists, most state that water is pale blue. The wavelength absorbed is not retained, but the one left gives an object its color. Water is colorless, odorless and tasteless due to natural factors that are inevitable, for example preventing light from being refracted back, giving taste buds supplements to combine with proteins for effective tasting.
