Disodium hydrogen phosphate (secondary sodium phosphate), Na ₂ HPO ₄ , is a colorless, very slightly water-soluble crystalline salt. It exists anhydrous and with 2 moles (density 2.066 gcm ^-3 , loss of water at 95 °), 7 moles (density 1.68 gcm ^-3 , melting point 48 ° with loss of 5 H ₂ O) and 12 moles water ( Density 1.52 gcm ^-3 , melting point 35 ° with loss of 5 H ₂ O) becomes anhydrous at 100 ° C and, upon increased heating, passes into the diphosphate Na ₄ P ₂ O ₇ . Disodium hydrogen phosphate is prepared by neutralization of phosphoric acid with soda solution using phenolphthalein as an indicator. Dipotassium hydrogen phosphate (secondary or dibasic potassium phosphate), K ₂ HPO ₄ , is an amorphous, white salt that is readily soluble in water. Trisodium phosphate, tertiary sodium phosphate, Na ₃ PO ₄ , are colorless crystals which have a density of 1.62 gcm ^-3 as dodecahydrate and a melting point of 73-76 ° C (decomposition), as decahydrate (corresponding to 19-20% P ₂ O ₅ ) have a melting point of 100 ° C and in anhydrous form (corresponding to 39-40% P ₂ O ₅ ) have a density of 2.536 gcm ^-3 . Trisodium phosphate is readily soluble in water under alkaline reaction and is prepared by evaporating a solution of exactly 1 mole of disodium phosphate and 1 mole of NaOH. Tripotassium phosphate (tertiary or tribasic potassium phosphate), K ₃ PO ₄ , is a white, deliquescent, granular powder of density 2.56 gcm ^-3 , has a melting point of 1340 ° and is readily soluble in water with an alkaline reaction. It arises z. Example, when heating Thomasschlacke with coal and potassium sulfate. Despite the higher price, the more soluble, therefore highly effective, potassium phosphates are often preferred over the corresponding sodium compounds in the detergent industry. Tetrasodium diphosphate (sodium pyrophosphate), Na ₄ P ₂ O ₇ , exists in anhydrous form (density 2.534 gcm ^-3 , melting point 988 °, also indicated 880 °) and as decahydrate (density 1.815-1.836 gcm ^-3 , melting point 94 ° with loss of water) , For substances are colorless, in water with alkaline reaction soluble crystals. Na ₄ P ₂ O ₇ is formed by heating disodium phosphate to> 200 ° or by adding phosphoric acid with soda reacted in stoichiometric ratio and the solution is dehydrated by spraying. The decahydrate complexes heavy metal salts and hardness agents and therefore reduces the hardness of the water. Potassium diphosphate (potassium pyrophosphate), K ₄ P ₂ O ₇ , exists in the form of the trihydrate and is a colorless, hygroscopic powder with a density of 2.33 gcm ^-3 , which is soluble in water, the pH being 1% Solution at 25 ° 10.4. Condensation of the NaH ₂ PO ₄ or of the KH ₂ PO ₄ gives rise to relatively high molecular weight sodium and potassium phosphates, in which one can distinguish cyclic representatives, the sodium or potassium metaphosphates and chain-type, the sodium or potassium polyphosphates. In particular, for the latter are a variety of names in use: melting or annealing phosphates, Graham's salt, Kurrolsches and Madrell's salt. All higher sodium and potassium phosphates are collectively referred to as condensed phosphates. The technically important pentasodium triphosphate, Na ₅ P ₃ O ₁₀ (sodium tripolyphosphate), is an anhydrous or with 6 H ₂ O crystallizing, non-hygroscopic, white, water-soluble salt of the general formula NaO- [P (O) (ONa) -O] _n -Na with n = 3. In 100 g of water dissolve at room temperature about 17 g, at 60 ° about 20 g, at 100 ° around 32 g of the salt water-free salt; after two hours of heating the solution to 100 ° caused by hydrolysis about 8% orthophosphate and 15% diphosphate. In the preparation of pentasodium triphosphate, phosphoric acid is reacted with sodium carbonate solution or sodium hydroxide solution in a stoichiometric ratio and the solution is dehydrated by spraying. Similar to Graham's salt and sodium diphosphate, pentasodium triphosphate dissolves many insoluble metal compounds (including lime soaps, etc.). Pentakalium triphosphate, K ₅ P ₃ O ₁₀ (potassium tripolyphosphate), is marketed, for example, in the form of a 50% strength by weight solution (> 23% P ₂ O ₅ , 25% K ₂ O). The potassium polyphosphates are widely used in the washing and cleaning industry. There are also sodium potassium tripolyphosphates which can also be used in the context of the present invention. These arise, for example, when hydrolyzed sodium trimetaphosphate with KOH: (NaPO ₃ ) ₃ + 2 KOH → Na ₃ K ₂ P ₃ O ₁₀ + H ₂ O
