Water color can reveal physical, chemical and bacteriological conditions. In drinking water, green can indicate copper leaching from copper plumbing and can also represent algae growth. Blue can also indicate copper, or might be caused by syphoning of industrial cleaners in the tank of commodes, commonly known as backflowing.
To ensure consistency and repeatability, the methods use in the chemical analysis of water samples are often agreed and published at a national or state level. By convention these are often referred to as "Blue book". [4] [5] Certain analyses are performed in-field (e.g. pH, specific conductance) while others involve sampling and laboratory ...
The term "water quality" more broadly refers to many characteristics of water, including temperature, dissolved oxygen, the amount of nutrients, or the presence of algal blooms. How clear the water appears is only one component of water quality. [1] [5] [47] An underwater ecosystem can have high water clarity yet low water quality, and vice versa.
The polarized form of the water molecule, H + OH −, is also called hydron hydroxide by IUPAC nomenclature. [106] Water substance is a rare term used for H 2 O when one does not wish to specify the phase of matter (liquid water, water vapor, some form of ice, or a component in a mixture) though the term "water" is also used with this general ...
Nomenclature of Organic Chemistry, commonly referred to by chemists as the Blue Book, is a collection of recommendations on organic chemical nomenclature published at irregular intervals by the International Union of Pure and Applied Chemistry (IUPAC).
Kelley Blue Book, Edmunds and NADA are all great tools to determine your car value. The best tool is a personal decision and depends on what you are trying to accomplish by valuing your vehicle ...
The clear liquid remaining above the precipitated or the centrifuged solid phase is also called the supernate or supernatant. The notion of precipitation can also be extended to other domains of chemistry ( organic chemistry and biochemistry ) and even be applied to the solid phases (e.g. metallurgy and alloys ) when solid impurities segregate ...
Whether upgrading to a newer model or downsizing your fleet, knowing the true value of your car is important information for maximizing its resale potential. This figure is useful when choosing an...
