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.
CN- + H+ ----> HCN
Yes and no. HCN is a salt, but it is also a weak acid.
Acid + base conjugate base + conjugate 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
The conjugate acid of F- is HF.
HNO2 conjugate acid = one more hydrogen conjugate base = one less hydrogen

The conjugate base and conjugate acid for HS04 is: Conjugate acid is H2SO4 Conjugate base is SO42
The conjugate acid is the acetic acid, CH3COOH.
Its conjugate acid is H3O+
The conjugate acid of H2O is H3O+
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.
You mean,HCO3 - = bicarbonateH2CO3 = carbonic acid and the conjugate of the above base.
