Why is boric acid considered as a weak acid ?

Text Solution

Verified by Experts

Fluorine has the greatest affinity for hydrogen, due to the large electro negativity difference between them, forming HF which is associated due to the hydrogen bonding . Hydrofluoric acid is a weak acid whereas the other hydrohalic acid are strong acids.
......H - F ..... H - F ..... H - F
It takes tremendous amount of energy to break the strong H-F bond in water.
