Which one of the following is the weakest acid in water
Correct answer: A. HF
- A. HF
- B. HCl
- C. HBr
- D. HI
Explanation
While HF is the weakest acid in water among the given options, it's important to remember that it's still a highly corrosive and dangerous acid.Here's the breakdown of acid strength in water among the hydrogen halides:HF < HCl < HBr < HI (weakest to strongest)Reason for HF's Weakness:Strong H-F bond: HF has an exceptionally strong bond between hydrogen and fluorine due to fluorine's high electronegativity and small size. This strong bond makes it more difficult for HF to dissociate (break apart) in water to release H+ ions, which is a key characteristic of strong acids.
