1. What is the difference between trisodium phosphate and sodium dihydrogen phosphate?
Trisodium phosphate (Na₃PO₄) contains three sodium ions and is strongly alkaline in aqueous solution. Sodium dihydrogen phosphate (NaH₂PO₄) contains two hydrogen ions and one sodium ion, with weakly acidic aqueous solution.
2. Is trisodium phosphate harmful to the human body?
Low toxicity, but avoid inhalation of dust or direct contact with skin. Protective equipment recommended during operation.
Trisodium phosphate is mainly produced by:
H₃PO₄ + 3NaOH → Na₃PO₄ + 3H₂O
Finished product obtained through concentration, crystallization and drying
NaH₂PO₄ + 2NaOH → Na₃PO₄ + 2H₂O
