KCN = K(+) + CN(-)
then CN(-) + H2O = HCN + OH(-) hydrolysis that's why solution of potassium cyanide in water is alkaline

KCN (s) → K+(aq) + CN- (aq)
Dissociation is complete as shown in the equation. You did not ask for more than that, and in any case, KCN is the salt formed when KOH and HCN are reacted to neutralise each other.
KCN is a simple ionic compound that is soluble in water to about 50 g/l @25̊C - stable

KCN(s) + H2O ===> K+ + OH- + HCN
HCN is a weak acid (only slightly ionized), so the solution is alkaline.
