Phosphoric Acid Application
|
Industry
|
Phosphoric Acidused in removing dust from the metal surfaces.
Used as rust converter by bringing it in direct contact with a rusted iron,
or steel tools and other surfaces that are rusted.
It is helpful in cleaning the mineral deposits, cement nous smears and hard water stains.
|
|
Food
|
Used to acidify the foods and beverages such as colas.
|
|
Medicine
|
Phosphoric Acid is an important ingredient in over the counter medications to combat nausea.
|
|
Dentistry
|
Phosphoric Acid is mixed with zinc powder and forms zinc phosphate, and it is useful in temporary
dental cement. In orthodontics, zinc is used as an etching solution to help clean and roughen the
surface of teeth.
|
|
Fertilizer
|
Used as reaction fertilizer in the soil around a granule acidification is generated that improves the
utilization of phosphorus applied and available in the rhizosphere. Due to its nitrogen content
(present as ammonia), it is good for crops that require these nutrients in its initial phase
