# need help doing titration watch

1. I know how to do the actual titration but its the table that I need help on. I don't know how to do it. could someone tell me how to make the table, that will be so helpful

I heard that you should include, initial reading, final reading, titre reading (something like that) but dont know what to include in them.
2. For each run - initial volume, final volume, difference in volume (i.e. titre), all labelled with the same units at the top of the columns (normally cm^3).
You'll have at least 4 rows - the trial, and the three actual runs (or however many it takes to get concurrent titres). Label them as Trial, 1, 2 and 3.
I never included the average as part of the table itself, I just did the calculation and gave the value directly underneath.
Hope this helps!
EDIT - my teacher was always really keen on us doing the table inside a box, not with open sides. Helped keep everything neat and tidy!
3. Your table would appear, albeit with carefully drawn lines courtesy of a ruler, look like this:

You're reading from the titre so you could include "titre" in the headings though I doubt it would be necessary. I'm not sure whether an average is required but I'm sure you'll be able to deduce how to add that in for yourself.
4. Things to keep in mind:
- Keep a 'trial' column.
- Don't redraw the table and continue lines down the page - use a rubber - Examiners don't like it
- Always keep units and keep them consistent (cm^3)
- When you average, refer to it as the mean
Titre (unit)
Average (unit)
Or any combination of this table. Providing it has those basic components, you're away.
5. oh thanks guys. hopefully I do good. And I heard that you have to put your answers in 1dp or was it 2? e.g. if the solution in your titre stopped at 23.2cm^3, would you write it down as 23.2 or 23.25/23.20 (.25 if it looks more than halfway to 23.4, .20 if it looked less than halfway to 23.2cm^3)

You should always record measurements appropriate to the accuracy with which you have measured. If you measure something to 2 decimal places you should NEVER record it to 1 dp.

So, for example, a burette reading of 22.20 ml must NOT be recorded as 22.2 ml as this gives an incorrect idea of the degree of accuracy.
7. I thought it was a degree of precision if it's 22.2 and 22.20?
