The color of a water sample can be reported as: Apparent color is the color of a body of water being reflected from the surface of the water, and consists of color from both dissolved and suspended components. Apparent color may also be changed by variations in sky color or the reflection of nearby vegetation.
Predicting the color of a compound can be extremely complicated. Some examples include: Cobalt chloride is pink or blue depending on the state of hydration (blue dry, pink with water) so it is used as a moisture indicator in silica gel. Zinc oxide is white, but at higher temperatures becomes yellow, returning to white as it cools.
The dark brown water in the inland waterways contains high concentrations of CDOM. As this dark, CDOM-rich water moves offshore, it mixes with the low CDOM, blue ocean water from offshore. Colored dissolved organic matter (CDOM) is the optically measurable component of dissolved organic matter in water.
Cloudy urine is only a symptom, not a disease, says Dr. Ramin. “So once a person has cloudy urine, we have to determine what the source of the cloudy urine is.”
Apr. 4—Mililani Mauka's public water supply is fine, in quantity and quality, a Board of Water Supply spokesperson says. Question : Is the Board of Water Supply aware that residents in Mililani ...
In other words, as light passes through a greater distance of water color is selectively absorbed by the water. Color absorption is also affected by turbidity of the water and dissolved material. Water preferentially absorbs red light, and to a lesser extent, yellow, green and violet light, so the color that is least absorbed by water is blue ...
On a cloudy day, there is simply less light penetrating the ocean waters, not enough light to cause sufficiently visible backscatter back into the atmosphere from water molecules and impurities (which makes the blue color visible when viewing a surface of water rather than viewing water in transmission).
