The ph of a solution containing 0.818 m acetic acid
(ka1.76*10-5) ans 0.172 m sodium acetate is?

Explanation:

It is known that the relation between pH and is as follows.

              pH =

and,    

Hence, first we will calculate the value of as follows.

                               =

                               = 4.75

Now, we will calculate the value of pH as follows.

              pH =

                    =      

                    = 4.75 + (-0.677)

                    = 4.07

Therefore, we can conclude that the pH of given solution is 4.07.
