1. The problem statement, all variables and given/known data A solution of [tex]NH_4F[/tex] would be: a) acidic b) neutral c) basic 3. The attempt at a solution I think the solution would be acidic because it is a salt made of a weak acid and a weak base. Since the Ka for HF is greater than the Kb for NH3, the Ka for NH4+ is greater than the Kb for F-. Thus, the solution is acidic. Am I right?
