The pH of 0.20 M HF (Hydrofluoric acid) is 3.27. Whereas, [H₃O⁺] for the same is 6.8 X10 ⁻⁴

<h3>What is Hydrofluoric acid?</h3>

A hydrogen fluoride and water solution is hydrofluoric acid. HF solutions are colorless, corrosive, and acidic. The majority of fluorine-containing chemicals are made using it; examples include the substance PTFE and the widely used psychiatric drug fluoxetine. Aluminum, plastics, electrical components, pharmaceuticals, high-octane fuel, fluorescent light bulbs, and refrigerants are all made with hydrogen fluoride. The production of refrigerants uses 60% of the hydrogen fluoride used in manufacturing. corrosive due to the acid's H+ ions and poisonous due to the fluoride ions F-, which can penetrate deeply, chelate calcium and magnesium, and thus upset biological balances due to the destruction of the skin's or an eye's outermost layer.
