acidity in inorganic

Well,organic.HF is a weak acid,due to its property of high intermolecular hydrogen bonding capability.
and H₂O self ionises into H⁺ and OH^-,which nullify each other's acidic and basic properties respectively.Also,cn think this way, H⁺+OH^-→H₂O i.e. reaction of a strong acid with a strong base giving a neutral salt.

@AIEEEE .....this is a very fundamental mistake that i also made while facing the qs. for the first time......hydrogen bonding mainly affects boiling point and solubility. intramol h-bond can affect affect acidity but there is no scope of intramol h-bond in any of the given compounds.....so think something else.......the answer is relatively simple !!!

H₂O ---> H+ + OH-

HF ---> H+ + F-

F- is weak base than OH- so its conj. acid r different so H₂O is weak acid as compared 2 HF

sorry for the mistake.
actually,the bond energy of H-F bond is very high,which increases their bond strength

thats the answer !!!!!!!! simple !!!!!!!!
