Answer:

Because it is TOO reactive a metal.........and in fact you don't even add it to water.........

Explanation:

We can write the stoichiometric reaction.............

#K(s) + HCl(aq) rarr KCl(aq) + 1/2H_2(g)uarr#

This would occur with a lot of spits and sparks even if water were used instead of hydrogen chloride...............Potassium is often used as a drying agent in stills..........and when the still is eventually cleaned, the potassium residues have to be carefully destroyed.
