Hydrofluoric acid (HF) can be dissolved in pure water. Will the pH of the solution be greater or less than 7? Explain.

The pH of Hydrofluoric acid (HF), when dissolved in pure water, would be less than 7.

Explanation:

Hydrofluoric acid is a corrosive acid that is undoubtedly a weak acid. HF not being strong acid is because it does not dissociate in water completely. Also, the chemical bond between hydrogen and fluorine is a polar covalent bond.

It polar covalent bond makes this acid pH less than seven because the mixture would lead to the pH level of water to decrease. Hence the pH 7 is neutral

Less than 7 because considering Ph7 = neutral and Ph2 = acidic, the mixture would cause the water Ph to decrease
