Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water and is a precursor to almost all fluorine compounds. This leads to protonation of very strong acids like hydrochloric, sulfuric, or nitric when using concentrated hydrofluoric acid solutions. At high concentrations, HF molecules undergo homoassociation to form polyatomic ions (such as bifluoride, HF 2) and protons, thus greatly increasing the acidity. HFis a liquid or gas which is the most corrosive acid known when in concentratedform. 3.3.10 Hydrofluoric Acid. sgt_blocking_layer.style.opacity=0; sgt_blocking_layer.style.MozOpacity=0; this.document.getElementById('fpu_suggestion_form_div').style.display="inline"; sgt_blocking_layer.style.zIndex="-100"; At concentration of 1 mM, it has a pH of 3.27, At concentration of 10 mM, it has a pH of 2.65, At concentration of 100 mM, it has a pH of 2.12. apopupdiv.style.MsTransition="all 1s ease-in-out"; s = s.replace( /\u00BE/g, '3/4' ); sgt_blocking_layer.style.MozOpacity=0; Make a suggestion. popupdiv= this.document.getElementById(popupdivname); Pain associated with exposure to solutions of HF (1-50%) may be delayed for 1-24 hours. } {/eq} solution. } s = s.replace( /\u2122/g, 'TM' ); s = s.replace( /\u203A/g, '>' ); background-color: #000000; Ð¡ommentâ¦ Calculate the pH of a 0.200 M HF solution.
