If you mixed 5.50 mL of the acidic solution with 6.79 mL of the basic solution, what should be the pH of the resulting solution?
Dima020 [189]

Answer : The  pH of the resulting solution is 4.6

Explanation : Given,

pK_a=4.757

Activity coefficient for acetic acid = 1.000

Activity coefficient for acetate ion = 0.775

Ionic strength = 0.10 M

To calculate the pH of resulting solution we are  using Henderson Hesselbach equation :

pH=pK_a+\log \frac{[Salt]}{[Acid]}

Now put all the given values in this expression, we get:

pH=4.757+\log (\frac{0.775\times 0.10}{1.000\times 0.10})

pH=4.6

Thus, the pH of the resulting solution is 4.6
