An acid of krypton is formed when krypton tetrafluoride is slowly hydrolyzed by ice at —30° to —60°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° to 5°C in a yield of approximately 7 percent by weight.
