Extremely off result for titration (1 Viewer)

[leesh95]

I am titrating NaOh and oxalic acid at school and got extremely weird results
1. 27 mL
2. 26.6 mL
3.26 mL
4.25.5 mL
5. 25.3mL

For the last three I was extremely careful, washed out my equipment very carefully and added the oxalic acid through a burette drop by drop.

Can I take an average of these results and and accept it as the final answer. I'm unsure because they are really off.

Those answers are fine, just take an average and talk about it in your discussion.

It would be weird if they were 15 or 20 mL out, 2 or 3 is fine.

Remember that your first result should always be excluded because it's used as an ESTIMATE to find the equivalence point.
