Hcn pka
WebThe pKa of a strong acid is less than zero. pKa is the negative log base ten of the Ka value, to be precise (acid dissociation constant). It determines an acid’s strength, or how tightly a proton is held by a Bronsted acid. ... HCN 4.9 x 10-10 9.3; Hydrofluoric acid HF 6.8 x 10-4 Web28 apr 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 ( …

WebExpert Answer. pKa=−logKa Principle: The lower the pKa value, the stronger the acid. HClO …. Given the pKa values of the following acids arrange their conjugate bases in order of increasing base strength: HClO2 (pKa = 1.96), HNO2 (pKa = 3.40), HCN (pKa = 9.21). The weakest base should be given first and the strongest last.
