WebFeb 2, 2024 · Because of the use of negative logarithms, smaller values of pKa correspond to larger acid ionization constants and hence stronger acids. For example, nitrous acid ( HNO2 ), with a pKa of 3.25, is about a 1000 times stronger acid than hydrocyanic acid … WebAug 4, 2014 · Fun! weak acid versus weak base! Ammonium cyanide, $\ce{NH4CN}$, is a solid where the atoms are grouped into the same ions that are generated in solution: $\ce{NH4+}$ and $\ce{CN-}$.Although it can be sublimed with very mild warming, it is fairly unstable. In particular it reacts with atmospheric water vapor, evolving ammonia and HCN.
Web-is a weak base because it is the conjugate base of a weak acid. Conjugate bases of weak acid are also weak, therefore, the do no fully dissociate in solution.
