The acid is HCN.
HCN - Hydrogen cyanide The conjugate acid of CN- is HCN. HCN stands for hydrogen cyanide. The conjugate acids are a combination of a strong acid and a low base.
The conjugate base of CN- is HCN (hydrogen cyanide). When CN- accepts a proton, it becomes neutral and forms the weak acid HCN.
Yes and no. HCN is a salt, but it is also a weak acid.
NH3 + H20 <----> NH4+ + OH- Ammonia is a weak base so it is the favored side of the equilbrium. Conjugate acid and base pairs only differ by a proton. So ammonia and ammonium are pairs and water and hydroxide ions are pairs. NH4+ + CN- <-------> HCN + NH3
It is weakly acidic but extremely poisonous, though. ;)
The conjugate base of hydrocyanic acid (HCN) is cyanide ion (CN-). When HCN donates a proton, it forms CN-.

H+ + cn- ---> hcn

The eqnet ionic equation is HCN + OH- --> H2O + CN-
The net ionic equation for the reaction is: CN^- + H^+ -> HCn
NaCN doesn't really have a pKa. In water it becomes Na^+ and CN^-. The CN^- is a base so it will have a Kb and pKb. If you want the pKa of the conjugate acid (HCN), you can find that from 1x10^-14/Kb.
Sodium cyanide is a base/salt that dissociates in water. CN- is a conjugate base of a weak acid so it grabs a proton (in small amounts) from the water molecule to become HCN.
hydrogen(H) and cyanide(CN) which is a polyatomic ion (made up of more than one element)
