Read More. No 130-40-5) occurs as the dihydrate in yellow to orange-yellow crystals. The phosphoric acid units can be bonded together in rings (cyclic structures) forming metaphosphoric acid molecules. Its structure is shown in the illustration. In Metaphosphoric acids, each phosphorus has an oxidation state of +5. But phosphoric acid units can bind together into rings or cyclic structures, chains (catenas), or branched structures, with various combinations possible. (1). Sodium Metaphosphate is the general term for any polyphosphate salt with four or more phosphate units. This is (HPO3)3. Physical Properties The number of P-0-P bonds in cyclic metaphosphoric acid is (A) two (B) zero (C) three (D) four. Each of the double bonds on the O atoms has one sigma bond, and one pi bond. It can be deprotonated to form cyclic metaphosphate anions and has applications in biochemistry, agriculture, pharmacy, and chemical research.
