Jackson grinned sardonically "Nah, not really interested, maybe some other time."
"Nah. Him I can handle," Jenn said.
In the case of sodium dihydrogen phosphate, NaH 2 PO 4 H 2 O, a stable rhombic form is obtained from warm solutions, while a different, unstable, rhombic form is obtained from cold solutions.
Since the reaction with the acid salts is attended by liberation of nitric acid: NaH 2 PO 4 +3AgNO 3 = Ag3P04+NaN03 +2HN03, Na 2 HPO 4 +3AgNO 3 =Ag 3 PO 4 + 2NaN03+HNO 3, it is necessary to neutralize the nitric acid if the complete precipitation of the phosphoric acid.
Being a tetrabasic acid it can form four classes of salts; for example, the four solium salts Na 4 P 2 0 7, Na3HP207, Na 2 H 2 P 2 0 7, NaH 3 P 2 0 7 are known.
Sodium hydride, NaH, is a crystalline substance obtained directly from sodium and hydrogen at about 400°.
The name Altona is said to be derived from allzu-nah (" all too near"), the Hamburgers' designation for an inn which in the middle of the 16th century lay too close to their territory.
