Acid of Krypton and Its Barium Salt

Science. 1964 Jan 17;143(3603):242-3. doi: 10.1126/science.143.3603.242.

Abstract

An acid of krypton is formed when krypton tetrafluoride is slowly hydrolyzed by ice at -30 degrees to -60 degrees C. The yield is 2 to 3 percent (mole). A barium salt of this acid, thermally stable at room temperature, is formed by the hydrolysis of krypton tetrafluoride with a 0.35N solution of barium hydroxide at O degrees to 5 degrees C in a yield of approximately 7 percent by weight.
