#"Potassium hydroxide and dihydrogen gas."#


Potassium is an alkali metal. It is much more reactive than sodium, whose reactions yu may have seen.

We can represent its reaction with water by the following equation:

#K(s) + H_2O(l) rarr KOH(aq) + 1/2H_2(g)#

This reaction proceeds with a lot of spits and sparks.
