Fluoroantimonic acid is the strongest superacid based on the measured value of its Hammett acidity function (H0), which has been determined for various ratios of HF: SbF5.

Jan 1, 2025 · Carborane acids are the strongest known single-component acids on Earth, whereas fluoroantimonic acid is the most potent mixed acid.

Jan 21, 2021 · The world’s strongest acid is fluoroantimonic acid, one of the superacids. Superacids are so powerful they aren’t even measured using the regular pH or pK A scales.

Sep 29, 2023 · Fluoroantimonic acid registers an H of -21, while sulfuric acid's H measures -12. To translate that, fluoroantimonic acid is a staggering 20 × 10¹⁹ times stronger than pure sulfuric acid.

Read this guide to learn what the 7 strong acids are, why they’re important, and why they’re not necessarily the most dangerous acids you’ll be working with in the lab.

Jun 9, 2025 · The strongest acid in the world is fluoroantimonic acid, a superacid so powerful that it can react with almost anything, even materials like glass.

Dec 1, 2025 · Learn how true acid strength is measured, why water limits definition, and the identity of the world’s most powerful superacid.

May 23, 2025 · Superacids (e.g., Fluoroantimonic Acid – HSbF₆): Formed by combining hydrogen fluoride (HF) with antimony pentafluoride (SbF₅), this is the strongest acid ph—millions of times …

Oct 11, 2024 · Discover the power of superacids, the strongest acids in the world. Learn about their uses and properties in our in-depth guide.

Jun 2, 2024 · Fluoroantimonic acid is the world’s strongest acid, proudly standing on the pedestal slightly above carborane. However, there’s still an ongoing debate as to whether carborane is the strongest …
