Calculating uncertainty
« on: March 23, 2007, 11:43:37 PM »
I know this will be a ridiculously easy question for someone but I can not find the answers.
I need to know how to calculate the uncertainty for a titration lab report I have to hand in.

We are given the uncertainties for the equipment such as the buret, flask, etc.

Now,I need to create a table for the initial, final, and total volume readings and their corresponding uncertainties (ie, V1, V2, Vf). 

The initial volume and final volume are the readings on the buret, final being the difference between them.  I've got that. 

So, for V1, I record the buret reading and the buret uncertainty. 

For V2, (final volume) I'd again record the buret reading and its uncertainty.  However, do I have to account for the uncertainty of the flask??  Since the two solutions are now titrated, I'd think the uncertainty of both the flask and buret need to be accounted for is this correct?

The total volume would again include both uncertainties of the buret and the flask, right?
