All phosphates are insoluble except for group IA metals and (NH4)3PO4
Diammonium hydrogen phosphate is more soluble in water compared to monoammonium phosphate. This is because diammonium hydrogen phosphate has two ammonium ions, which increases its overall solubility in water.
The formula for hydrogen phosphate ion is: H2PO4−
Hydrogen phosphate is also known as dihydrogen phosphate.
Another name for aqueous hydrogen phosphate is phosphate ion.
The Chemical Formula of diammonium hydrogen phosphate is (NH4)2.HPO4
Diammonium hydrogen phosphate is more soluble in water compared to monoammonium phosphate. This is because diammonium hydrogen phosphate has two ammonium ions, which increases its overall solubility in water.
The addition of acid increases the solubility of calcium phosphate because it helps to break down the compound into its individual ions, making it easier for the compound to dissolve in water. Acidic conditions provide hydrogen ions that react with the calcium phosphate, leading to the formation of more soluble products.
HPO4 does not exist. HPO42- would be the dibasic form of phosphoric acid and be the hydrogen phosphate ion. H3PO4 also exists and is phophoric acid. So if two moles of NaOH were reacted with phosphoric acid 2Na+ HPO42- would be formed disodium hydrogen phosphate.
The solubility in water is higher than 10 g/L.
The formula for hydrogen phosphate ion is: H2PO4−
Lithium Hydrogen Phosphate or Lithium biphosphate
The solubility of calcium phosphate in water is generally low, with reported values ranging from around 1-20 ppm. However, the solubility can vary depending on factors such as pH, temperature, and the specific form of calcium phosphate present.
The formula for lithium hydrogen phosphate is Li2HPO4.
Hydrogen phosphate is also known as dihydrogen phosphate.
The correct answer is sodium monohydrogen phosphate.
Another name for aqueous hydrogen phosphate is phosphate ion.
Na2HPO4 is disodium phosphate or disodium hydrogen phosphate.
