How much mL of 0.2 M NaOH are needed to titrate vinegar while doing a titration with Phenolphthalein?
Sorry It should be 10.00 ml of vinegar!!!
What is the strength of vinegar you are using?
It is just vinegar that we did in the class. We used about 55 ml of vinegar to titrate.
I can show you how to solve the problem but I have no numbers. However,
mL vin x M vin = mL NaOH x M NaOH
If you substitute mL vinegar and multiply by M vinegar (molarity = mols/L) and divide by M NaOH you can calculate mL NaOH. Most vinegars are about 5% acetic acid and I believe that is % w/v which makes it about 0.833 M.
