HF is diatomic in the gas phase. As a liquid, HF forms relatively strong hydrogen bonds, hence its relatively high boiling point. Solid HF consists of zigzag chains of HF molecules.

Solutions of HF are colorless, acidic and highly corrosive. A common concentration is 49% (48–52%) but there are also stronger solutions (e.g. 70%) and pure HF has a boiling point near room temperature.

Jul 12, 2021 · Hydrogen fluoride (HF) is an extremely toxic, corrosive gas and liquid. As the lightest of the hydrogen halides, it has a surprisingly high boiling point, higher even than that of hydrogen iodide.

Hydrofluoric acid, a solution of hydrogen fluoride gas (HF) in water, is one of the most corrosive and dangerous chemicals encountered in the laboratory. Exposure to HF can cause severe tissue …

- For small fires involving UN 1790, hydrofluoric acid (HF), use carbon dioxide, dry chemical, dry sand, or alcohol-resistant foam. - For large fires involving UN 1790, use water spray, fog, or alcohol …
