WebIf the water is boiling, the phosphorus(V) chloride reacts further to give phosphoric(V) acid and more HCl. Phosphoric(V) acid is also known just as phosphoric acid or as orthophosphoric acid. POCl 3 + 3H 2 O H 3 PO 4 + 3HCl. The overall equation in boiling water is just a combination of these: PCl 5 + 4H 2 O H 3 PO 4 + 5HCl WebMelting points. The amino acids are crystalline solids with surprisingly high melting points. It is difficult to pin the melting points down exactly because the amino acids tend to decompose before they melt. Decomposition and melting tend to be in the 200 - 300°C range. For the size of the molecules, this is very high.
