Depends on the context. Technically, phosphorus is an element (P), and phosphate is a molecular anion (PO4_3-), part of phosphoric acid (H3PO4). In (medical) diagnostic testing, they're often used interchangeably, sometimes called "inorganic phosphorus." It's also an essential plant nutrient, so on fertilizers you'll see the phosphorus content expressed as a percentage (by weight) measured as P2O5, the anhydride of phosphoric acid.
No, trisodium phosphate (TSP) and tripotassium phosphate are different compounds. Trisodium phosphate contains three sodium (Na) atoms and one phosphate (PO4) group, while tripotassium phosphate contains three potassium (K) atoms and one phosphate group. They have different chemical properties and applications.
The compound with formula Na3PO4 is named "sodium phosphate", "trisodium phosphate", "sodium ortho-phosphate", or "trisodium ortho-phosphate".
The compound name for K3PO2 is potassium hypophosphite.
Trisodium phosphate works to remove grease by breaking down the grease molecules through a process called saponification. This causes the grease to become water-soluble and easier to wash away. Additionally, trisodium phosphate is highly alkaline, which helps to cut through and dissolve the grease.
When trisodium phosphate is dissolved in water, it produces a solution whose pH can be up to 12.5; as an acid is a chemical whose pH is below 7, trisodium phosphate cleaner doesn't contain any acid.
Phosphoric acid reacts with trisodium phosphate to form sodium dihydrogen phosphate and disodium hydrogen phosphate. This reaction involves the exchange of ions between the two compounds, resulting in the formation of new salts.
The chemical formula for tripotassium phosphate is K3PO4, which represents a compound containing three potassium (K) ions and one phosphate (PO4) ion.
K3PO4
The compound with formula Na3PO4 is named "sodium phosphate", "trisodium phosphate", "sodium ortho-phosphate", or "trisodium ortho-phosphate".
The name trisodium phosphate is incorrect for the compound Na3PO4 because trisodium phosphate actually refers to the compound Na3PO4.12H2O, which contains water molecules in addition to the phosphate group. The correct name for the compound Na3PO4 is sodium phosphate.
Trisodium phosphate can typically be purchased at hardware stores, home improvement stores, or online retailers. It is commonly used as a cleaning agent or stain remover.
Trisodium Phosphate
Trisodium phosphate is an ionic compound. It is composed of sodium cations (Na+) and phosphate anions (PO4^3-), which are held together by electrostatic forces of attraction.
Na3PO4 It is more properly called trisodium phosphate.
The compound name for K3PO2 is potassium hypophosphite.
