WebMay 8, 2016 · You are correct, HCl is a stronger acid than HF. Fluorine is both more electronegative and smaller than chlorine. Because fluorine is more electronegative, the bond between it and the hydrogen is more polar, meaning that the proton would need to overcome a larger coulomb force to separate from the fluorine.

WebThis limit on the acid strength of solutes in a solution is called a leveling effect. To measure the differences in acid strength for “strong” acids, the acids must be dissolved in a solvent that is less basic than water. In such solvents, the acids will be “weak,” and so any differences in the extent of their ionization can be determined. WebHCN is formed in interstellar clouds through one of two major pathways: [49] via a neutral-neutral reaction (CH 2 + N → HCN + H) and via dissociative recombination (HCNH + + e − → HCN + H). The dissociative recombination pathway is dominant by 30%; however, the HCNH + must be in its linear form.

WebSince HOCℓ is a stronger acid than HCN, then OCℓ– is a stronger base than CN–. The dissociation (or ionization) of HOCℓ in water is HOCℓ + H2O ≡ HCℓ + 2OH–. The pH of a 0.10 M solution of acetic acid (Ka = 1.8 x 10-5) will be higher than the pH of a 0.10 M solution of formic acid (Ka = 1.8 x 10-4).
