With reference to the Hydrogen fluoride, consider the following statem...
Statement 1: It is an extremely poisonous and corrosive liquid.
Hydrogen fluoride (HF) is indeed an extremely poisonous and corrosive liquid. It is highly toxic and can cause severe burns on contact with the skin, eyes, and respiratory system. HF is a strong acid that can easily penetrate the skin and react with calcium ions in the body, leading to the formation of insoluble calcium fluoride. This reaction can cause deep tissue damage and result in long-lasting injuries.
Statement 2: It is formed when the Fluorspar is treated with sulphuric acid at a high temperature.
This statement is also correct. Hydrogen fluoride can be produced by treating fluorspar (calcium fluoride, CaF2) with sulfuric acid (H2SO4) at a high temperature. The reaction can be represented as follows:
CaF2 + H2SO4 → 2HF + CaSO4
In this reaction, fluorspar reacts with sulfuric acid to produce hydrogen fluoride and calcium sulfate. Hydrogen fluoride is a colorless gas that readily dissolves in water to form hydrofluoric acid, which is the liquid form of HF.
Conclusion:
Both statements 1 and 2 are correct. Hydrogen fluoride is indeed an extremely poisonous and corrosive liquid, and it is formed when fluorspar is treated with sulfuric acid at a high temperature.

With reference to the Hydrogen fluoride, consider the following statem...
Recently, scientists from the University of Oxford have come up with a new way to obtain fluorine atoms, used to manufacture important chemical compounds used in industry and research, in a much safer and less energy-intensive way.
- Fluorine comes from a calcium salt called calcium fluoride, or fluorspar.
- Fluorspar is mined and then treated with sulphuric acid at a high temperature to release hydrogen fluoride (HF).
- Hydrogen fluoride is then made to react with other compounds to create fluorochemicals.
- Fluorine is a highly reactive element used to make fluorochemicals.
- It is used to produce plastics, agrochemicals, lithium-ion batteries, and drugs.
- Issues with hydrogen fluoride
- A major downside of this process is that HF is an extremely poisonous and corrosive liquid that irritates the eyes and respiratory tract even at low concentrations.
- It also requires special transportation and storage requirements.
- Hydrogen fluoride spills have occurred numerous times in the last decades, sometimes with fatal accidents and detrimental environmental effects.
Hence both statements are correct.
