Question

K(s)+H2O ---->????

Answer 1

This is formally a redox reaction....

Explanation:

Potassium is an active alkali metal, that is capable of being oxidized by the water molecule....

`stackrel(0)K(s) + stackrel(+I)H_2O(s) rarr stackrel(+I)KOH(aq) + 1/2stackrel(0)H_2(g)uarr`

Now you do this sodium, and the reaction is pretty zippy. You do with potassium, a more potent reductant, and this is even zippier...
