Alloys of Potassium and Sodium






Potassium and sodium unite to an alloy of the formula Na2K. In absence of air at 200° to 250° C., potassium reacts with sodium hydroxide to form a liquid alloy NaK2:
3K+NaOH = KOH+NaK2.

At 350° C. sodium and potassium hydroxide interact in accordance with the equation

3Na+2KOH = 2NaOH+NaK2.

At 225° to 275° C. the reaction is different, and is expressed by the equation

2Na+KOH = NaOH+NaK. On exposure to air these alloys ignite instantly.
