They trapped a mixture of atmospheric air with additional oxygen in a test-tube (A) upside-down over a large quantity of dilute alkali solution (B), which in Cavendish's original experiment was potassium hydroxide,[14] and conveyed a current through wires insulated by U-shaped glass tubes (CC) which sealed around the platinum wire electrodes, leaving the ends of the wires (DD) exposed to the gas and insulated from the alkali solution. points) What is Pr(T; > 2X2 = 4? He was then left with a gas that would not react and when he examined its spectrum he saw new groups of red and green lines, confirming that it was a new element. The alkali absorbed the oxides of nitrogen produced by the arc and also carbon dioxide. The first argon compound with tungsten pentacarbonyl, W(CO)5Ar, was isolated in 1975. Argon may be used as the inert gas within Schlenk lines and gloveboxes. The name "argon" is derived from the Greek word , neuter singular form of meaning 'lazy' or 'inactive', as a reference to the fact that the element undergoes almost no chemical reactions.
