It has been used in the past as a pesticide and in fireworks. Ca(OH)_2 + H_3PO_4 -> Ca_3(PO_4)_2 + H_2O (unbalanced) Writing calcium hydroxide + phosphoric acid yield calcium phosphate + water in chemical equation would be, Ca(OH)_2 + H_3PO_4 -> Ca_3(PO_4)_2 + H_2O but it still needs to be balanced. [Medline]. There are three hydrogen atoms, one phosphorus atom, and four oxygen atoms. Other common names include WP and the slang term "Willie Pete" or "Willie Peter" derived from William Peter, the World War II phonetic alphabet for … This means it is an inorganic type of acid. When a syringe or a double-tipped needle (cannula) is used in handling pyrophoric reagents, the assembly should be rinsed with an inert (non-reacting) solvent and the rinse transferred to a flask under an inert atmosphere for subsequent neutralization. But it merely affects the rate of neutralization. 6) A spill of phosphoric acid is hazardous to both your health and the environment, however, and even used carefully it must still be neutralized and cleaned. This virtually eliminates the danger of phosphorus auto-ignition. Amongst our 2765 admissions between 1984 and 1998, 326 patients had chemical burns.
