FALSE! Lower pH values coordinate to MORE acidic solution. A pH of 7 is neutral, so a pH of 8 is actually a basic solution.
The Correct choice is A. H+ , F- and HF
Since HF is a weak acid, it behaves like an weak electrolyte in water. so, there is incomplete dissociation of HF in water. Therefore, there will be HF molecules present in the solution along with the ions ~
Answer: D
