Remember, if you don't get them all done today in class, then you WILL HAVE TO STAY AFTER SCHOOL in order to finish!
When doing your calculations, make sure you use the UNROUNDED number so it's as close to accurate as possible.also, your values have to be within %5 of each other
That might be a problem... 0 vinegar titrations so far.

if you over titrate by ONE DROP, you can add one drop of vinegar/one grain of KHP to put it back to normal.
remember to get as close to 3.0ml of vinegar as possible
Round to the tenth decimal!
make sure you record everything!
Make sure that the titrations aren't too dark or Dr. Bautista will be upset
dont forget to clean up your area after spilling NaOH and other chemicals in your working areas
make sure you show all of your calculations in your lab notebook
try to be as exact as possible on your calculations as you may have to go back and re-do titrations
Don't forget that when calculating, your values MUST be within at least 5% of each other, or they do not count.
remember to put all of your lab equations in neat order with corresponding numbers in order to gain partial credit
