Phosphoric acid or orthophosphoric acid, is a common inorganic acid, is a medium-strong acid.
Phosphoric acid or orthophosphoric acid, is a common inorganic acid, is a medium-strong acid.Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as a rust resistance agent, food additives, dental and orthopedic surgery, EDIC preservatives, electrolytes, welding flux, dispersants, industrial preservatives, fertilizer as raw materials and component home cleaning products.Can be also used as a chemical reagent.
Phosphoric acid can soluble in ethanol.
Phosphoric acid in different temperature，its solubility is different.
392.2 g/100 g (−16.3 °C)
369.4 g/100 mL (0.5 °C)
446 g/100 mL (15 °C)
548 g/100 mL (20 °C)
The dominant use of phosphoric acid is for fertilizers, consuming approximately 90% of production.
Food-grade phosphoric acid (additive E338) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. The phosphoric acid also serves as a preservative. Soft drinks containing phosphoric acid, which would include Coca-Cola, are sometimes called phosphate sodas or phosphates. Phosphoric acid in soft drinks has the potential to cause dental erosion.Phosphoric acid also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously.
Specific applications of phosphoric acid include:
Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary. In evaluating the controls present in your workplace, consider: how hazardous the substance is, how much of the substance is released into the workplace and whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible.
This chemical should be stored in a metallic or coated fiberboard container using a strong polyethylene inner package.
It’s actually more common to have too much phosphorus than not enough. Phosphorus is found naturally in many foods and phosphoric acid is used as an additive, so most people get enough in their diet.
Your body needs phosphorus, but too much of it can cause problems. StudiesTrusted Source suggest that excessive phosphorus intake can put you at risk for osteoporosis and heart disease. Calcium and phosphorus work together to form and maintain healthy teeth and bones. The minerals need to be balanced in order to be effective.
Too much phosphorus can decrease the amount of calcium in your body, leading to bone loss. It can also impair your body’s ability to use other minerals, such as iron, zinc, and magnesium.
Phosphoric acid is dangerous if you come into contact with it as a chemical substance. The toxic fumes can irritate your skin, eyes, and respiratory system.
The recommended daily amount (RDA) of phosphorus needed for normal bodily function is 700 mg. You can get this easily from natural food sources. Foods that are high in protein are usually high in phosphorus as well. This means additional phosphoric acid from processed food and soda is likely more than the body needs.
Because so many of us drink sodas and eat processed foods, some health professionals are concerned about the American diet when it comes to phosphoric acid. For example, one soda may have up to 500 mg of phosphoric acid. People who take in 4,000 mg per day of phosphorus are considered at high risk for negative health effects associated with phosphorus.
Adults with kidney disease are recommended to have no more than 800 to 1,000 mg of phosphorus a day. Kidneys help the body get rid of extra phosphorus, but too much phosphorus can build up in the blood if they’re not functioning well.
Phosphoric acid can be very hazardous in the case of skin contact, eye contact, and ingestion. It can also cause irritation if vapors are inhaled. This chemical can cause damage to the skin, eyes, mouth, and respiratory tract. Because of the potential hazards posed by this chemical, it is important to use care when handling it.
Repeated or prolonged exposure to phosphoric acid mist can lead to chronic eye irritation, severe skin irritation, or prolonged respiratory tract issues. To protect your health when handling this potentially hazardous chemical, it is important to use caution in the form of personal protective equipment (PPE).
