I would say A because it’s the only one that doesn’t conduct electricity. Ionic compounds conduct electricity, and covalent compounds do not.

The ph of a solution containing 0.818 M acetic acid<br> (ka1.76*10-5) ans 0.172 M sodium acetate is?
kvasek [131]

Explanation:

It is known that the relation between pH and pK_{a} is as follows.

              pH = pK_{a} + log \frac{[salt]}{[acid]}

and,     pK_{a} = -log K_{a}

Hence, first we will calculate the value of pK_{a} as follows.

                   pK_{a} = -log K_{a}

                               = -log (1.76 \times 10^{-5}

                               = 4.75

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

              pH = pK_{a} + log \frac{[\text{sodium acetate}]}{\text{acetic acid}}

                    = 4.75 + log \frac{0.172}{0.818}      

                    = 4.75 + (-0.677)

                    = 4.07

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