Sodium or Potassium Aluminates can be made by dissolving aluminum foil or cans in
warm aqueous sodium or potassium hydroxide solution:
"2 Al(s) + 2 K+ (aq) + 2 OH- (aq) + 6 H2O(l) -> 2 K+ (aq) + 2 Al(OH)4- (aq) + 3H2 (g)"
"Cut about 1g (�0.01 g) of aluminum metal from your can. Use steel wool to remove material coating the aluminum and cut the aluminum into very small pieces. Place these in a 150-mL beaker. Add 25 mL of 4 M KOH to the aluminum pieces cautiously. "
"Warm the beaker gently to initiate the reaction. Gas is evolved in this reaction; make sure this reaction occurs in a well-ventilated area. What gas is generated? When no further reaction of aluminum is evident, gravity filter the warm solution to remove any insoluble impurities."
Is any of the H2 "Hydrino Hydride"?
The second part of an experiment would consist of adding hot distilled/deionized water to
the aluminate solution while doing calorimetry to see if there is any exothermal activity, especially
if the new mix is heated.
An interesting side note"
"The chemistry of concentrated sodium aluminate solutions stored in many of the large, underground storage tanks containing high-level waste (HLW) at the Hanford and Savannah River Nuclear Reservations is an area of recent research interest. Not only is the presence of aluminate in solution important for continued safe storage of these wastes, the nature of both solid and solution aluminum oxy-hydroxides is very important for waste pretreatment. Moreover, for many tanks that have leaked high aluminum waste in the past, little is known about the speciation of Al in the soil. In this study, Raman spectroscopy has been used to investigate the speciation of the aqueous species in the Al2O3 -- Na2O -- H2O system over a wide range of solution compositions and hydration."
And relating to hydrogen generation in rad waste tanks:
"Executive Summary"
"The purpose of this report is to review recent progress made in determining the chemical mechanisms, kinetics, and stoichiometry of gas generation in Hanford waste tanks. Information has been gathered from the results of laboratory studies with simulated wastes, laboratory studies with actual waste core samples (Tanks SY-101 and SY-103), studies of thermal and radiolytic reactions in the gas phase, and gas solubility evaluations. In-tank gas composition data are also briefly reviewed."
Interesting, Jones?
