Potassium phosphate K3PO4
Phosphorus oxide and potassium react to form potassium phosphite, K2HPO3. This compound is commonly used as a fertilizer and fungicide for agricultural purposes.
The common name of this compound is phosphorus pentaoxide and the systematic name is Potassium(V) Oxide.
The chemical formula for potassium oxide is K2O. It is composed of two potassium atoms and one oxygen atom.
Potassium oxide is a compound. Compounds are pure substances that contain more than one type of atom. Since potassium oxide contains potassium and oxygen atoms, it is a compound. Elements are pure substances that contain only one type of atom, such as oxygen gas.
Potassium oxide is a ionic lattice which is made out of potassium ions and oxide ions. Therefore, separate 'molecules of this compound do not exist. The empirical formula itself is K2O which is used also as the chemical formula for the compound.
The compound name for K2O is potassium oxide.
The name of P2O5 is diphosphorus pentoxide. Its chemical formula is P2O5.
The chemical symbol for phosphorus oxide is P2O5.
Three potassium oxides are known: K2O, KO2, K2O2.
K2O2 is the molecular formula for the compound potassium peroxide. Since both potassium (K) and oxygen (O) have a subscript of "2", a potassium peroxide molecule contains two potassium atoms and two oxygen atoms.
We know that K2O is the chemical formula for potassium oxide.
Phosphorus pentoxide or phosphorus(V) oxide.
