Will NH4F be acidic, basic or neutral in water?

GIven: pKb NH3=4.75. KaHF=6.6*10^-4.

I found for NH4F to be acidic by finding Ka (NH3) being greater than Kb (HF).

What is the final pH of a solution that has 0.123M of NH4F?

For each of the following salt solutions,indicate whether the solution will be acidic, basic orneutral.
Then using data given below, calculate [OH^-] or[H₃O⁺] and pH for each solution.

(a) 0.11 M NaF(K_a (HF) = 5.0 x 10^-04)
1(acidic, basic, or neutral)

[OH^-] = 2 M
pH = 3

(b) 0.20 MNH₄Cl(K_b (NH₃) = 2.0 x10^-05)
4(acidic, basic, or neutral)

[H₃O⁺] = 5 M
pH = 6
