WebNov 1, 2024 · The pH value of a normal SBF should remain approximately 7.4. As shown in Fig. 4 (a), the pH value of SBF immersing F3 gently changed in the range from 7.3 to 7.6 during immersion time to 49 days. However, the pH value of SBF immersing the naked magnesium alloy soared in the initial 4 days, and then kept stable at 10.4. WebFluoroantimonic acid is the strongest superacid based on the measured value of its Hammett acidity function (H 0), which has been determined for various ratios of HF:SbF 5. The H 0 of HF is −15. A solution of HF containing 1 mol % of SbF 5 is −20. The H 0 is −21 for 10 mol%. For > 50 mol % SbF 5, the H 0 is between −21 and fairport knife sharpening
