Hydrofluoric Acid HF: With a pKa of 3.15 HF is considered a weak acid in that it is not full disassociated below a pH of about 5.5 and will form complexes with many compounds including itself. Unlike other mineral acids, hydrofluoric acid will attack glass, concrete, rubber, quartz and alloys containing silica. The chemical itself is a clear, colorless chemical that has a number of physical, chemical, and toxicological properties that make it very hazardous to handle. function q_hide_f_popup(popupdivname) Determine the pH of a 0.15 M aqueous solution of KF. popupdiv.style.MsTransition="all 1s ease"; Hydrofluoric acid 40% Suprapur®; Synonym: Hydrofluoric acid solution, Fluoric acid; find Supelco-1.00335 MSDS, related peer-reviewed papers, technical documents, similar products & more at Sigma-Aldrich. s = s.replace( /\u201c|\u201d|\u201e/g, '"' ); document.getElementById('fpu_suggestion_postsubmit_div').style.display="inline"; "pH" = 2.39 Hydrofluoric acid, "HF", is a weak acid that does not ionize completely in aqueous solution to form hydronium cations, "H"_3"O"^(+), and fluoride anions, "F"^(-). {/eq}, {eq}\rm{}Ka = \frac{ [F^-][H_3O^+] }{ [HF] } Safety of Hydrofluoric acid vs. ammonium-bifluoride.
