In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
Sometimes pyrophosphate, tripolyphosphate, tetrapolyphosphate, etc. are called diphosphate, triphosphate, tetraphosphate, etc., especially when they are part of phosphate esters in biochemistry. They are also used for scale and corrosion control by potable water providers . [ 6 ]
A phosphate, occasionally or colloquially called phosphate soda, [1] [2] is a type of beverage flavored with a tangy or sour taste, using phosphoric acid as additive. [ 3 ] These beverages appeared in the 1870s, following the advent of development by Harvard professor Eben N. Horsford of a process for "acid phosphates of lime" (patented 1868 ...
Phosphates have low toxicity in the environment but cause nutrient pollution, a major water quality problem in many watersheds. [17] Phosphates in water cause eutrophication of algae which creates conditions favorable to formation of harmful algal blooms. These blooms prevent light and oxygen from getting into the water, leading to the death of ...
Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy. The production of fertilizer is the largest source responsible for minerals mined for their phosphate content.
That's why we've come up with a list of the best ... formaldehyde, peroxide, chlorine or phosphates. Instead, it's water-based and pH-balanced to work on carpets, clothes, linens and upholstery ...
Elemental phosphorus is distilled out of the furnace and burned with air to produce high-purity phosphorus pentoxide, which is dissolved in water to make phosphoric acid. [22] The thermal process produces phosphoric acid with a very high concentration of P 2 O 5 (about 85%) and a low level of impurities.
So-called 'night moving' companies help them disappear without a trace and start a new life somewhere else. ... While the cause was linked to the use of white phosphorus within 5 years, it took ...
