What is the pH of an acetic acid solution where the concentration of acetic acid is 2 mM and the concentration of sodium acetate
schepotkina [342]

Answer:

pH = 5.76

Explanation:

We can solve this problem by using<em> Henderson-Hasselbach's equation</em>:

pH = pKa + log\frac{[SodiumAcetate]}{[AceticAcid]}

We are already know all the required information, thus we<u> input the data given by the problem</u>:

pH = 4.76 + log(20/2)

And finally <u>calculate the pH</u>:

pH = 5.76

The pH of that acetic acid solution is 5.76.
