What is Calcium Phosphate? ; Properties of Calcium Phosphate – Ca3(PO4)2 ; Uses of Calcium Phosphate
Calcium phosphate is a mineral found in bones and teeth and is also used as a dietary supplement. It is a white powder that is insoluble in water. It is slightly soluble in dilute acids and is soluble in alkalis. It is used as a fertilizer, in food production, and in toothpaste.
Characteristics of Calcium Phosphate
Calcium phosphate is a mineral found in the body and is also a component of bone. It is also known as hydroxyapatite. Calcium phosphate is a salt of calcium and phosphate. It is white and crystalline and has a salty taste. It is soluble in water and is insoluble in alcohol.
Calcium Phosphate Preparation
Calcium phosphate can be prepared by reacting calcium oxide with phosphoric acid, according to the following equation:
CaO (s) + H 3 PO 4 (aq) → Ca 3 (PO 4 ) 2 (aq) + H 2 O (l)
The calcium phosphate precipitate can be collected by filtering the reaction mixture, and the precipitate can be dried to produce the desired product.
Structure of Ca3(PO4)2
The structure of Ca3(PO4)2 is composed of Ca2+ cations and PO4 3- anions. The Ca2+ cations are arranged in a cubic structure, while the PO4 3- anions are arranged in a tetrahedral structure. There is a total of eight Ca2+ cations and sixteen PO4 3- anions in the structure.
Solubility of Calcium Phosphate Ca3(PO4)2 in water
The solubility of calcium phosphate in water is about 1.5 grams per 100 milliliters at room temperature.
Occurrence of Calcium Phosphate in Soils
In soils, calcium phosphate (Ca3(PO4)2) is a mineral that is found in small quantities. It is an important plant nutrient, and is used by plants to form structural components of their cells. It is also necessary for the plants to uptake other nutrients from the soil.
Calcium phosphate is not very soluble in water, so it is not often found in the soil’s water-soluble fraction. It is more likely to be found in the soil’s solid fraction, where it is bound to other minerals or to organic matter.
Calcium phosphate is not very mobile in soils, so it can be difficult for plants to uptake it from the soil. When it is available, plants will absorb it from the soil through their roots. It can also be absorbed by plants through their leaves, if it is present in a soluble form.

Health Hazards of Calcium Phosphate
Calcium phosphate is a mineral that is found in the body and is also a component of many foods. It is also used as a dietary supplement and is available in pill form. Calcium phosphate is used to treat and prevent bone loss, and to improve bone health. It is also used to improve dental health.
There are some health hazards associated with calcium phosphate. It can cause constipation, and it can also interfere with the absorption of other minerals, such as iron and zinc. It can also increase the risk of kidney stones.
