Answer 2

HF and HMnO₄ are acids in the given options.

HF is a weak acid and  HMnO₄ is a strong acid.

• A molecule or other component that may participate in reactions by donating a proton or accepting an electron pair is called an acid.
• According to the Bronsted-Lowry theory, "a base is a proton acceptor and an acid is a proton donor."
• According to Lewis' concept of acids and bases, "acids act as electron-pair acceptors and bases as electron-pair donors."
• The pH scale stands for "potential of hydrogen" and is used to determine a substance's acidity or basicity.
• A hydrogen fluoride (HF) and water solution is hydrofluoric acid. HF solution is colorless, corrosive, and acidic.
• Since H and F have a very strong bond, HF doesn't dissociate very much in the water. Since full dissociation is the primary trait of a strong acid, HF is regarded as a weak acid.
• HMnO₄ is the permanganate salts' conjugate acid.
• permanganic acid is formed when HMnO4 is deprotonated to produce permanganates, which have a deep purple color.
