Is it actually possible to dispose of a body with hydrofluoric acid?

WebIn that scenario, I believe C B r X 3 X − dissociates more easily than C F X 3 X −, meaning C F X 3 X − is more stable. Note: This logic wouldn't apply to the instance of H O X − vs. H S X − because H S X − is more stable than H O X − (even though H − O bond length is shorter than H − S bond length). acid-base. stability ...

Amongst the haloacids, only H F is weak. Acid strength can be determined by the stability of the conjugate base (for most acids, the conjugate base is what you get when you remove H X + from the acid). In this case the conjugate bases are the halides. itf 56a

"WebIn the Brønsted–Lowry definition of acids and bases, an acid is a proton (H⁺) donor, and a base is a proton acceptor. When a Brønsted–Lowry acid loses a proton, a conjugate base is formed. Similarly, when a Brønsted–Lowry base gains a proton, a conjugate acid is formed. " - Is hf base

WebMay 8, 2016 · HCl is a stronger acid than HF because fluorine is more electronegative than chlorine. I'm thinking this is true, because since fluorine is more electronegative than chlorine, it has a higher ionic energy and therefore a stronger bond between hydrogen than chlorine does with hydrogen. ...
