What neutral ionic compound is composed of calcium ions and phosphate ions?
The neutral ionic compound composed of calcium ions and phosphate ions is calcium phosphate. Its chemical formula is Ca3(PO4)2, indicating that three calcium ions (Ca²⁺) combine with two phosphate ions (PO4³⁻) to achieve electrical neutrality. This compound is commonly found in various biological systems, including bone and teeth.
What precipitate forms when potassium phosphate and calcium acetate are mixed?
When potassium phosphate and calcium acetate are mixed, a precipitate of calcium phosphate forms. This occurs because calcium ions (Ca²⁺) from calcium acetate react with phosphate ions (PO₄³⁻) from potassium phosphate, resulting in the formation of calcium phosphate, which is insoluble in water. The reaction can be represented by the equation: 3 Ca(CH₃COO)₂ + 2 K₃PO₄ → Ca₃(PO₄)₂ (s) + 6 CH₃COOK.
Will calcium phosphate precipitate?
Calcium phosphate can precipitate under certain conditions, typically when the concentrations of calcium ions and phosphate ions in a solution exceed their solubility product (Ksp). This often occurs in biological systems, such as in the formation of bone and teeth, or in industrial processes. Factors such as pH, temperature, and the presence of other ions can influence the precipitation process. If conditions favor supersaturation, calcium phosphate will crystallize out of the solution.
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 formula for Ca2 and P3?
The formula for calcium ions is Ca²⁺, indicating that calcium has a +2 charge. For phosphate ions, the formula is PO₄³⁻, which shows that the phosphate ion carries a -3 charge. When combining these ions to form a neutral compound, the formula for calcium phosphate is Ca₃(PO₄)₂, reflecting the ratio needed to balance the charges.
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.
What neutral ionic compound is composed of calcium ions and phosphate ions?
The neutral ionic compound composed of calcium ions and phosphate ions is calcium phosphate. Its chemical formula is Ca3(PO4)2, indicating that three calcium ions (Ca²⁺) combine with two phosphate ions (PO4³⁻) to achieve electrical neutrality. This compound is commonly found in various biological systems, including bone and teeth.
What mixes with potassium phosphate to make a precipitate?
Potassium phosphate can form a precipitate when mixed with solutions containing calcium ions, such as calcium chloride. The reaction between potassium phosphate and calcium ions leads to the formation of calcium phosphate, which is insoluble in water and precipitates out of the solution. Other metal ions, such as magnesium or barium, may also lead to similar precipitation reactions.
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.
What precipitate forms when potassium phosphate and calcium acetate are mixed?
When potassium phosphate and calcium acetate are mixed, a precipitate of calcium phosphate forms. This occurs because calcium ions (Ca²⁺) from calcium acetate react with phosphate ions (PO₄³⁻) from potassium phosphate, resulting in the formation of calcium phosphate, which is insoluble in water. The reaction can be represented by the equation: 3 Ca(CH₃COO)₂ + 2 K₃PO₄ → Ca₃(PO₄)₂ (s) + 6 CH₃COOK.
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.
Will calcium phosphate precipitate?
Calcium phosphate can precipitate under certain conditions, typically when the concentrations of calcium ions and phosphate ions in a solution exceed their solubility product (Ksp). This often occurs in biological systems, such as in the formation of bone and teeth, or in industrial processes. Factors such as pH, temperature, and the presence of other ions can influence the precipitation process. If conditions favor supersaturation, calcium phosphate will crystallize out of the solution.
