Uses of Phosphoric Acid By: Want To Know It

Phosphoric acid is mineral acid which molecules that can combine themselves in a number of different ways. These different combinations are referred to as phosphoric acids. Phosphoric acid is a white solid that melts to form a colorless, viscous liquid. High concentrations of the liquid are corrosive. Phosphoric acid is non-flammable and non-toxic. Let’s examine what phosphoric acid is used for in the world today. Uses of Phosphoric Acid •Phosphoric acid is used as a rust converter. When the solution in liquid or gel form is placed directly on rusted areas of steel, steel tools or steel surfaces, the rust is converted from the red oxide to a black ferric phosphate. This is common when pickling steel. After the rust has been converted to black ferric phosphate it can easily be scrubbed off. •Food grade phosphoric acid is used to carbonate beverages such as cola. The phosphoric acid creates a tangy or sour taste. •Phosphoric acid is used in dentistry as an etching solution. It cleans and roughens the surface of the teeth when applying dental apparatus such as braces or when applying fillings. •It is also used in teeth whiteners to eliminate the plaque on teeth prior to the whitening process. •Phosphoric acid is also commonly used in over the counter anti-nausea medication. •Another common use is in pH balancing. It is used in plant fertilizers, nutrient solutions, in cosmetics and skin-care products to create the correct pH for the plants or skin. It is also used to neutralize the pH of water sources particularly aquariums. •Phosphoric acid is also used as a cleaning agent in the construction industry as its corrosive, non-toxic properties allow it to be used to removal mineral deposits, cement smears and hard water stains. Some household cleaners also use a safer and less strong chelant of phosphoric acid. Some detergents also make use of phosphoric acid as a dispersing agent. •It is used as an electrolyte in phosphoric acid fuel cells and when combined with distilled water in oxyhydrogen generators. •When heated it is used as an etching material to etch silicon nitride.

•Phosphoric acid is used by hobby welders as a flux to aid in soldering. Uses of Phosphoric Acid

Phosphoric acid or orthophosphoric acid is a mineral acid which is broadly known for its uses. This acid is made up of three hydrogen atoms, one phosphorus atom and four oxygen atoms. The chemical formula of this acid is H3PO4. This acid is very useful in industries and medicines. Here are some of the uses.:

Most commonly, it is used in removing dust from the metal surfaces. It is also used as rust converter by bringing it in Ads by Google direct with a rusted iron, or steel tools and other surfaces that are Magnetic Water Treatmentwww.deltawater.com.au rusted. It converts the ferric oxide Bore, River water problems, salt scale, corrosion Leading Aust Brand which is reddish-brown in color to black colored ferric phosphate.

Rust remover is found in liquid as well as gel form. In foods, phosphoric acid is used to acidify the foods and beverages such as colas. However, phosphoric acid is known to have an adverse on health. It has tangy or sour taste. It is low cost and easily available acid. Phosphoric acid is widely used in medicine and dentistry. It is an important ingredient in over the counter medications to combat nausea. These medications are high in sugars, namely glucose and fructose. For dental care, it 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. In certain types of fuel cells, phosphoric acid is used as an electrolyte. It is also helpful in cleaning the mineral deposits, cementinous smears and hard water stains. Learnin-education

Phosphoric acid that has many uses in industrial applications Phosphoric acid uses

Phosphoric acid is a compound with formula - (H3PO4). It is also called as ortho-phosphoric acid. It is a colorless, transparent and syrupy liquid which a neutral acid only soluble in water and ethanol. It is used most commonly in laboratory preparation of hydrogen halides. It is also used as a rust converter (often called naval jelly or rust killer) for converting rust into ferric phosphate. Thus it is efficient for removing rust. It is a chemical which is produced in large quantities in food industry. It is cheaply produced. Hence it can be used for providing sour or tangy taste to the processed food. Sometimes it is used for the extraction of citric acid in food industry. It is used in the medical field, basically by the dentists for the correction of irregularities of the teeth (orthodontics) and for dealing with the anatomy, development and diseases of the teeth (dentistry) as an etching solution. It is also used as a teeth whitener to eliminate plaque. It is also the basic constituent in over-the-counter anti-nausea medications which contains high levels of fructose and glucose.

Stating the industrial uses, phosphoric acid is also used as an external standard for phosphorus-31 nuclear magnetic resonance (NMR). In the industrial area it is required for the process used for separating mixtures due to differences in absorbency that is chromatography. It is useful in making phosphoric acid fuel cells, where in it is used as the electrolyte. If one puts two to three drops of phosphoric acid in a gallon of distilled water, it acts as electrolyte in oxy-hydrogen generators. Copper electro polishing is done by using phosphoric acid as an electrolyte. Also this form of phosphoric acid as an electrolyte is used for circuit board planarization and for filing rough edges on work piece. While carrying out the Wentworth Process for activated carbon production, phosphoric acid is used as oxidizing agent. It is a wet etching agent and hence is commonly used to make impressions on surface. To etch silicon nitride hot phosphoric acid is used in micro fabrication. Due to its defined properties phosphoric acid is also used by construction traders as a cleanser to remove mineral deposits on the sites. It can be used for removing hard water stains as well. It is also used as an aid to soldering in for example in model rail roaders. Phosphoric acid should be stored in a tight container and the area around should be cool, dry and well ventilated. Hence phosphoric acid is a chemical having abundant uses in industrial applications.
