Question

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
