Unbreakable gas June 26, 1886. The night is over the sky over Paris. The whole city has fallen asleep. Only the small house of the Paris Pharmacy School is still shining brightly.

Today, when he poured anhydrous hydrogen fluoride with potassium hydrogen fluoride into a U-tube made of platinum and passed a current to the platinum electrode, a light yellow odor-smelling gas was emitted at the anode. This gas is so lively and so invincible that even the crystalline silicic acid in it
