How many calcium ions in an 8.0 mole sample of calcium phosphate?
The formula unit for the most common form of calcium phosphate is Ca3(PO4)2. Therefore each formula unit, the ionically bonded counterpart of a mole for covalently bonded compounds, contains three calcium ions. The number of calcium ions in 8.0 "moles" of calcium phosphate is 3 [exact] X 8.0 X Avogadro's Number or 1.45 X 1025 atoms, where the depressed last digit of 1.45 indicates that this digit may not be significant. (The significant-digits-limiting datum is 8.0 moles.)
What is the difference between calcium carbonate and calcium phosphate?
CaCO3 = calcium carbonateCa3(PO4)2 = calcium phosphate
Is Ca3(PO4)2 soluble or insoluble in water?
Calcium phosphate, represented by the formula Ca3(PO4)2, is generally considered insoluble in water. Its low solubility is due to the strong ionic bonds between calcium ions and phosphate ions, which are not easily disrupted by water molecules. As a result, only a very small amount of calcium phosphate dissolves in water under normal conditions.
What is Hydroxyapatite crystals made of?
Hydroxyapatite crystals are made of calcium and phosphate ions. These crystals are the main mineral component of human bones and teeth, providing strength and rigidity to these structures.
What is a true statement regarding calcium in the bone matrix?
A true statement regarding calcium in the bone matrix is that it exists primarily in the form of hydroxyapatite crystals, which provide structural rigidity and strength to bones. These crystals consist of calcium phosphate and are integral to bone mineralization, facilitating the storage of calcium and phosphate ions. This mineralization process is crucial for maintaining bone density and overall skeletal health.
What are the constituent elements of calcium phosphate?
Calcium phosphate is composed of calcium and phosphate ions. The ratio of these ions can vary, leading to different types of calcium phosphate compounds such as hydroxyapatite and tricalcium phosphate.
What is the formula of the ionic compound that forms between calcium ions and phosphate ions?
The formula of the ionic compound formed between calcium ions (Ca^2+) and phosphate ions (PO4^3-) is Ca3(PO4)2, known as calcium phosphate. This compound forms due to the transfer of three calcium ions to two phosphate ions to achieve a neutral ionic compound.
What is the formula for the compound made from calcium and mono hydrogen phosphate ions?
Calcium hydrogen phosphate :) Ca2HPO4
What are the ions and crisscross method for lithium sulfide?
Lithium forms Li+ ions, and sulfur forms S2- ions. To determine the chemical formula for lithium sulfide using the crisscross method, you would cross the charges of the ions to get Li2S.
How the equivalent weight of calcium phosphate be calculated?
The equivalent weight of calcium phosphate is calculated by dividing the molar mass of calcium phosphate by the valency factor of the phosphate ion. Since calcium phosphate is a salt with the formula Ca₃(PO₄)₂, its molar mass is calculated by adding the molar masses of calcium and phosphorus (since there are three calcium ions and two phosphate ions in the formula). The valency factor of phosphate ion is 2 since it can donate or accept 2 electrons.
Is calcium phosphate a group of ions?
Yes: calcium cations and phosphate anions.
Is tricalcium phosphate ionic or covalent?
it is ionic because calcium is a metal and phosphorus is a gas.
What does calcium phosphate combine with?
Calcium phosphate can combine with various ions such as hydroxide, carbonate, and fluoride to form different compounds like hydroxyapatite, calcium carbonate, and calcium fluoride.
What would the ionic compound be for Ca and P?
The ionic compound for Ca and P would be calcium phosphate (Ca3(PO4)2). Calcium has a 2+ charge, and phosphate has a 3- charge, so two calcium ions are needed to balance out three phosphate ions.
How many calcium ions in an 8.0 mole sample of calcium phosphate?
The formula unit for the most common form of calcium phosphate is Ca3(PO4)2. Therefore each formula unit, the ionically bonded counterpart of a mole for covalently bonded compounds, contains three calcium ions.

How calcium and phosphate can make a compound with electroneutrality?
Calcium (Ca) has a 2+ charge and phosphate (PO4) has a 3- charge. To form a compound with electroneutrality, two phosphate ions will combine with three calcium ions. This results in the formation of calcium phosphate (Ca3(PO4)2), which is electrically neutral due to the balanced charges of the ions.
What is the ionic compound for Ca3(PO4)2?
The ionic compound for Ca3(PO4)2 is calcium phosphate. It consists of calcium ions (Ca2+) and phosphate ions (PO43-) in a 3:2 ratio.
