When we add weak acids to water, equilibrium between protonated and deprotonated forms of that acid exists.

In this case, hydrocyanic acid (HCN) reacts with water to form aqueous hydronium ions and aqueous cyanide anions.

We can write the dissociation reaction of HCN in water.

HCN(aq) H2O(l) HX3OX+(aq)+CNX(aq)\ce{HCN (aq) \xrightarrow {H_2O(l)} H3O^+(aq) + CN-(aq) }
