All of these metals react vigorously or even explosively with cold water. In each case, a solution of the metal hydroxide is produced together with hydrogen gas.
2X (s) + 2H2O (l) → 2XOH (aq) + H2 (g)
This equation applies to any of these metals and water - just replace the X by the symbol you want.
For your your reaction, the following would occur (written form and balanced equation):
Potassium + Water → Potassium Hydroxide + Hydrogen
2K + 2H2O → 2KOH + H2
2X (s) + 2H2O (l) → 2XOH (aq) + H2 (g)
This equation applies to any of these metals and water - just replace the X by the symbol you want.
