Practice question about equivalence point

[205743684]

Hi. I am a bit stuck on how to approach this question:

200mL of 1M Benzoic acid (C6H5COOH) is titrated with 1M NaOH. How much NAOH is needed to reach the equivalence point? kA of Benzoic acid is 6.5x10^-5 and benzoic acid is monoprotic.

If someone knows the steps to this, please let me know (:

Hey there!

The equivalence point is achieved when the moles of H+ are equal to the moles of OH-. As such you can use the formula M1V1 = M2V2 to determine how much NaOH is needed to reach the equivalence point.

I hope this helps!
