In my class I've recently conducted a titration using acetic acid and sodium hydroxide.
Our Ka value we found of acetic acid had a 93% error
We'd gotten 6.32 x 10 ^ -7
Most of the class also got 10^-7
What reasons could have caused this to occur ?
It has a huge percent error!

Please describe the procedure used for the experiment.

Actually calling it a 93% error is quite on understatement for a result that is almost two orders of magnitude away from the correct value. This is an artifact of the error definition used.
