Where did phosphoric acid come from?
Phosphoric acid is made from the mineral phosphorus, which is found naturally in the body. It works with calcium to form strong bones and teeth.
Where is phosphoric acid naturally found?
Phosphoric acid can be found in soft drinks, dairy products like milk, cottage cheese, and buttermilk, and other processed foods like cereal bars, flavored waters, bottled coffee beverages, and processed meats.
When was phosphorus discovered nearly three centuries ago?
In the year 1669, phosphorus was accidentally discovered in human urine as “a dark, unctuous, daubing mass” by Hennig Brandt, a merchant and alchemist of Hamburg, while searching for a liquid capable of transmuting silver into gold.
What is the main purpose of phosphoric acid?
phosphoric acid, also called orthophosphoric acid, (H3PO4), the most important oxygen acid of phosphorus, used to make phosphate salts for fertilizers. It is also used in dental cements, in the preparation of albumin derivatives, and in the sugar and textile industries.
Who invented phosphoric acid?
Phosphoric acid was discovered independently as a component of bone ash in 1770 by two Swedish chemists, Johann Gottlieb Gahn (1745–1818) and Karl Wilhelm Scheele (1742–1786). Four years later, Scheele discovered that the acid could be made by adding nitric acid to phosphorus.
Can you drink phosphoric acid?

Is phosphoric acid flammable?

Who was the first person to discover phosphoric acid?
As a liquid, phosphoric acid is a colorless, odorless, syrupy liquid whose character is sometimes described as sparkling. Phosphoric acid was discovered independently as a component of bone ash in 1770 by two Swedish chemists, Johann Gottlieb Gahn (1745–1818) and Karl Wilhelm Scheele (1742–1786).
Which is the most common form of phosphoric acid?
phosphoric acid, any one of three chemical compounds made up of phosphorus, oxygen, and hydrogen (see acids and bases). The most common, orthophosphoric acid, H3PO4, is usually simply called phosphoric acid.
How did Robert Boyle contribute to the discovery of phosphorus?
In the discovery of phosphorus, the British chemist Robert Boyle was almost at the same time as Kongkel, and also used a method similar to that of Kongkel to obtain phosphorus. Boyle’s student Codfrey Hanckwitz used this method to produce a larger amount of phosphorus in the UK and shipped it as a commodity to other European countries for sale.
Why was the method of phosphorus preparation kept secret?
Until 1737, the method of phosphorus preparation was kept secret. In the 17th century, a German businessman Pollant was obsessed with alchemy. He had heard that the “king of metal” gold could be made from urine, so he did a lot of experiments with urine for the purpose of making money.
