    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
