Physical description & handling notes

Large Crystals; Dry Powder
White solid, practically insoluble in water; [Merck Index]
White powder. Practically insol in water and in aq solns of pyrophosphates and hexametaphosphates. Sol in mineral acids. Does not form complexes with Fe(II), Fe(III), U(IV) salts. /Maddrell's salt (polymeric sodium metaphosphate)/
Sol in water (pH adjusted to 8-8.6). Insol in organic solvents. Possess dispersing and deflocculating properties, coagulate albumins, and inhibit the crystallinization of slightly sol compds such as calcium carbonate and calcium sulfate. /Glassy sodium metaphosphate; Graham's salt/
When heated to decomposition it emits toxic fumes of sodium oxide and phosphoxides.
Clear, hygroscopic glass. MP: 628 °C. Sol in water, but dissolves slowly. Depolymerizes in aqueous soln to form sodium trimetaphosphate and sodium orthophosphates. /Glassy sodium metaphosphate; Graham's salt/
