Question

Consider a 0.59 M solution of HF (K₂= 7.2 × 10-4).

Mark the major species found in the solution.
HF
F-
H+
OH-
H2o
Calculate the pH of this solution.
pH =
(the major species part is just true false)

Answer 1

The answer is 72.3481
Because you need to multiply the m by itself and then do 72x10-4
