What is the ph at 25°c of a solution that results from mixing equal volumes of a 0.0500 m solution of acetic acid and a 0.0367 m solution of sodium hydroxide? the pka of acetic acid is 4.74.

Hello!

We have the following data:

[acid] = 0.0500 M (mol/L)

[base] = 0.0367 M (mol/L)

pH of a buffer =?

knowing that pKa (acetic acid) = 4.74

Now, using the abovementioned data for the pH formula of a buffer solution or (Henderson-Hasselbalch equation), we have:

Note:. The pH <7, then we have an acidic solution.

I Hope this helps, greetings ... DexteR! =)
