Among the variety of acid takes the place of honor, and phosphoric acid.Its application in some areas of the industry for a long time paid off.
Meet phosphoric acid
What is the chemical?It is a liquid with virtually no color or shade of yellow.At room temperature, it exists as a crystalline solid rhombic shape.Typically such acid is a solution of 85% concentration, which is a liquid such as a syrup with a complete lack of smell.Phosphoric acid is readily soluble in water and many solvents.For example, in ethanol.If the heating temperature exceeds 213 degrees, the substance is converted to pyrophosphoric acid.
There are two varieties of this substance:
- food acid;
- industry.
Phosphoric acid: use
To date, the chemical demand in many areas of production.Where not only meets orthophosphoric acid.Its application can be divided into two types: in food and non-food industries.
Food phosphoric acid
This kind used for the manufacture of certain products.For example:
- As acidity regulator in the production of carbonated beverages.
- As acidulant in the composition of cheese and processed cheese.
- In the production of certain types of sausages.
- in baking as part razryhlitelnyh powders.
- In the manufacture of sugar.
This material in industrial production has its own designation - an antioxidant E338.
Non-food phosphoric acid
in many areas of production can not do without a component called phosphoric acid.The application needs to be:
- in agriculture.Especially in such industries as farming.A solution of this acid is included in the feed for the prevention of mink urolithiasis animals.
- In science, it is used for studies that are conducted in molecular biology.
- In production it is used as a flux for soldering of stainless steel, copper.
How to deal with the rust?
The answer is simple: you help phosphoric acid.The use of this material against rust corrosion protection.The thing is that it, unlike many others, is safe for metals.Processing phosphoric acid promotes the appearance of the surface protective film which prevents further damage.It often appears in the media, which are made to combat rust.Therefore, it is used in the hotel and restaurant business.
harm phosphoric acid
however (along with benefits), there are downsides to using phosphoric acid.
- It is able to increase the acidity of the body and thus upset the balance.
- It negatively affects calcium.It removes it from the bones and teeth.Earlier in dentistry to remove enamel often used phosphoric acid.Applying it recently banned for this reason.
