Calculate the ph of a solution that is 2.00 m hf, 1.00 m naoh, and 0.472 m naf. (ka=7,2×104)

Explanation:

The given data is as follows.

Concentration of acid, [HF] = 2 M

Concentration of salt, [NaF] = 0.472 M

Concentration of base, [NaOH] = 1.00 M

=

So, NaOH being a base will react with the acid that is, HF. And, according to Henderson-Hasselbalch equation we have he following.

             pH =

Also, we known that

so,                    

                          = 3.1426

Hence,    pH =

               pH = 2.5155

Thus, we can conclude that pH of the solution is 2.5155.

um i think it might be a car?

they are all solids.
